TRUE
This is because when you distribute 1 thing between 2 (or more) things, it (in a way) simplifies the problem...
For Example:
solve for x
f(x) = 5*(x - 4)
The only way to solve a question like this would be to distribute the 5 to the x and to the 4...
So...
The answer is: TRUE

Does 3.2 - 4d=2.3d+3 no solution or identity
The solution of expression is,
⇒ d = 5/16
We have to given that,
An expression is,
⇒ 3.2 - 4d = 2.3d + 3
Now, We can simplify the expression for solution as,
⇒ 3.2 - 4d = 2.3d + 3
Add 4d both side,
⇒ 3.2 - 4d + 4d = 2.3d + 3 + 4d
⇒ 3.2 = 6.3d + 3
Subtract 3 both side,
⇒ 3.2 - 3 = 6.3d
⇒ 0.2 = 6.3d
⇒ 6.3d = 0.2
Divide 6.3 both side,
⇒ d = 0.2/6.4
⇒ d = 20/64
⇒ d = 5/16
Thus, The solution of the expression is, d = 5/16

solve for n
4n + 2 = 6 (1/3n - 2/3)
The solution of expression for the value of n is, n = - 3.
Used the concept of expression that states,
Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that,
The expression is,
[tex]4n + 2 = 6 (\dfrac{1}{3} n - \dfrac{2}{3} )[/tex]
Now simplify the expression by combining like terms and apply the distributive property as,
[tex]4n + 2 = 6 (\dfrac{1}{3} n - \dfrac{2}{3} )[/tex]
Apply distributive property,
[tex]4n + 2 = (\dfrac{6}{3} n - \dfrac{12}{3} )[/tex]
[tex]4n + 2 = 2n - 4[/tex]
Combine like terms,
[tex]4n - 2n = - 4 - 2\\[/tex]
[tex]2n = - 6\\[/tex]
[tex]n = - 3[/tex]
Therefore, the value of n is - 3.

What is the solution to the compound inequality in interval notation? 2(x+3)>6 or 2x+3≤−7
Answer: The required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]
Step-by-step explanation: We are given to find the solution to the following compound inequality in interval notation :
[tex]2(x+3)>6~or~2x+3\leq -7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To find the solution to (i), we must solve both the parts separately.
The inequality (i) can be solved as follows :
[tex]2(x+3)>6\\\\\Rightarrow x+3>\dfrac{6}{2}\\\\\Rightarrow x+3>3\\\\\Rightarrow x>3-3\\\\\Rightarrow x>0\\\\\Rightarrow x\epsilon (0,\infty)[/tex]
or
[tex]2x+3\leq-7\\\\\Rightarrow 2x\leq-7-3\\\\\Rightarrow 2x\leq -10\\\\\Rightarrow x\leq -\dfrac{10}{2}\\\\\Rightarrow x\leq-5\\\\\Rightarrow x\epsilon(-\infty,-5].[/tex]
Thus, the required solution in interval notation is [tex](0,\infty)U(-\infty,-5].[/tex]
What is the measure of an exterior angle of a regular 7-sided polygon?
Enter your answer as a decimal in the box.
Round to the nearest tenth of a degree.
Answer: [tex]51.4^{\circ}[/tex]
Step-by-step explanation:
We know that the sum of all the exterior angles of a regular polygon with n sides is [tex]360^{\circ}[/tex].
The measure of an exterior angle of a regular n-sided polygon is given by :-
[tex]\dfrac{360^{\circ}}{n}[/tex]
Now, the measure of an exterior angle of a regular 7-sided polygon is given by :-
[tex]\dfrac{360^{\circ}}{7}=51.4285714286^{\circ}\approx51.4^{\circ}[/tex]
Hence, the measure of an exterior angle of a regular 7-sided polygon =[tex]51.4^{\circ}[/tex]

Please help me Factor -4d3 + 28d2 - 4d
Answer:
The factored form of the expression [tex]\( -4d^3 + 28d^2 - 4d \)[/tex] is [tex]\( -4d(d - 1)(d - 1)(6d - 1) \).[/tex]
Explanation:
To factor the expression [tex]\( -4d^3 + 28d^2 - 4d \)[/tex], we can first look for the greatest common factor (GCF) among the terms. In this case, the GCF is [tex]\( -4d \).[/tex]
So, we can factor out [tex]\( -4d \)[/tex] from each term:
[tex]\[ -4d(d^2 - 7d + 1) \][/tex]
Now, let's focus on factoring the quadratic expression inside the parentheses, [tex]\( d^2 - 7d + 1 \)[/tex]. To factor this quadratic expression, we need to find two numbers that multiply to give the constant term (1) and add to give the coefficient of the linear term (-7d). Since the constant term is 1, the only possible combination is 1 and 1.
So, we can rewrite the expression as:
[tex]\[ -4d(d^2 - 7d + 1) = -4d(d^2 - d - 6d + 1) \][/tex]
Now, we can group the terms and factor by grouping:
[tex]\[ -4d((d^2 - d) + (-6d + 1)) \][/tex]
[tex]\[ -4d(d(d - 1) - 1(6d - 1)) \][/tex]
Now, we can factor further:
[tex]\[ -4d(d - 1)(d - 1)(6d - 1) \][/tex]

Find length of MN such that LN = 5.7 and LM = 1.3 MN= x + 2.1
Final answer:
To find the length of MN, we can set up an equation using the fact that LN + LM = MN and substitute the given values. Solving for x, the length of MN is found to be 4.9 units.
Explanation:
To find the length of MN, we can use the fact that LN = 5.7 and LM = 1.3. We are also given that MN = x + 2.1. Since LN and LM are known, we can set up an equation using the fact that LN + LM = MN.
LN + LM = MN
5.7 + 1.3 = MN
Then, we can substitute the given value of MN = x + 2.1 into the equation and solve for x.
5.7 + 1.3 = x + 2.1
7 = x + 2.1
x = 7 - 2.1
x = 4.9
Therefore, the length of MN is 4.9 units.
If it takes six men six days to dig six holes, how long will it take one man to dig half a hole?
It will take 3 days for 1 man to dig half of that complete hole.
What are direct and inverse proportion ?Direct proportion if increase in one quantity also results in increase in another quantity for example price and weight of something.
Inverse proportion is when increase in one quantity results in decrease in another quantity for example time is inversely proportional to (speed when distance is constant.
According to the given question
6 men are working together then it takes them 6 days to dig 6 holes.
∴ Number of men days = 6 days × 6 men = 36 men days
So, in 36 men days 6 holes are dug. Now the men days and the number of holes being dug are in direct proportion with one another.
Hence number of men-days required to dig one hole
= 36/6 men days
= 6 men days
∴ No. of men days required to dig half a hole
= 6/2
= 3 men days
So, It takes 1 man 3 days to dig half a hole.

What is the factored form of 6n4 – 24n3 + 18n?
Answer:
Step-by-step explanation:
Notice to facts:
The numbers 6, -4 and 18 have a common factor: 6.In all the terms (n⁴, n³, n) are a factor n.The expression has a common factor 6n. Then,
6n⁴-24n³+18n = 6n(n³-4n²+3).
In order to factor the term n³-4n²+3 we use Ruffini-Horner rule, which gives us that
n³-4n²+3 = (n-1)(n²-3n-3).
Then,
6n⁴-24n³+18n = 6n(n³-4n²+3) = 6n(n-1)(n²-3n-3).

A taxi charges $2.50 for the first mile and $0.40 for each mile after that. The expression below shows how to find the total cost, in dollars, of a 20-mile taxi ride. 2.50 + 0.40 (20 - 1) What is the cost of the ride?
Answer:
Step-by-step explanation:
Alright , lets get started.
The first mile charge = [tex]$2.5[/tex]
Total miles taxi covered = [tex]20[/tex]
Subtracting first mile frm the total ride = [tex](20-1)[/tex]
Means the fare will apply on this mile.
So, cost of total ride = [tex]2.5 + 0.4 (20-1)[/tex]
cost of total ride = [tex]2.5+0.4*19[/tex]
cost of total ride = [tex]2.5+7.6[/tex]
cost of total ride = [tex]10.1[/tex]

Take -4 + 3a 2 from 7a - a 2
Subtracting [tex]\( -4 + 3a^2 \)[/tex] from [tex]\( 7a - a^2 \)[/tex] yields [tex]\( 7a - 3a^2 + 4 - a^2 \)[/tex], after distributing the subtraction and combining like terms.
To subtract [tex]\( -4 + 3a^2 \)[/tex] from [tex]\( 7a - a^2 \)[/tex], we need to distribute the subtraction across both terms in [tex]\( 7a - a^2 \)[/tex] and then combine like terms:
[tex]\[ (7a - a^2) - (-4 + 3a^2) \][/tex]
Distributing the subtraction:
[tex]\[ 7a - a^2 + 4 - 3a^2 \][/tex]
Now, combine like terms:
[tex]\[ (7a - 3a^2) + (4 - a^2) \][/tex]
So, the result of subtracting [tex]\( -4 + 3a^2 \)[/tex] from [tex]\( 7a - a^2 \)[/tex] is [tex]\( 7a - 3a^2 + 4 - a^2 \)[/tex].

Suppose you buy two sweaters. each sweater costs the same amount. the amount of money you spend varies directly with the number of sweaters you buy. if you spent $37.50 for two sweaters, what is the constant of variation?
Answer with Step-by-step explanation:
We spent $37.50 for two sweaters.
Each sweater costs the same amount.
Cost of each sweater=$37.50/2
=$18.75
The amount of money you spend varies directly with the number of sweaters you buy.
We have to find the constant of variation.
Here, cost of each sweater is the constant of variation.
Hence, constant of variation is:
$18.75
