how do you simplify radicals?
Answers
2) Separate the root expression into the two numbers you found as factors, with each number now under its own square root symbol. For example, sqrt(12) = sqrt(4) times sqrt(3).
3) Keep simplifying. The square root of a perfect square becomes just a number, without the radical square root symbol. sqrt(4)*sqrt(3) becomes 2*sqrt(3).
4) Check to see if anymore simplifying can be done, either by combining constants or finding another perfect square number that divides evenly into your factors. If no more simplifying can be done, you have your final "simplified radical form" (SRF) answer, 2*sqrt(3).
If there is a square root anywhere in the DENOMINATOR, you must "rationalize" the denominator, in other words, somehow get rid of the root in the bottom, in order for the expression to be considered simplest. For example, if you have 4/sqrt(2) you must use the trick of simplifying by multiplying the expression by sqrt(2)/sqrt(2). This will clear the square root in the bottom. If you multiply straight across, you would get 4*sqrt(2)/2, which simplifies again to 2*sqrt(2).
If you have a more complicated fraction with a square root in the denominator, like (4+sqrt(3))/(5-sqrt(3)), you will need to use the "conjugate" to simplify. This means multiplying top and bottom by the expression in the denominator, but with the middle sign flipped. Here you would multiply by (5+sqrt(3))/(5+sqrt(3)), multiply straight across on top and bottom using FOIL-ing and distribution. Some terms will cancel in the bottom, leaving you with a simpler denominator that has no square roots.

Step 4:
Answers
Step 1: Distributive Property. Step 2: Combine like terms. Step 3: Add 34x to both sides. Step 4: Divide by 17. x = 60/17.
Here's a step-by-step solution to the equation 2(10 - 13x) + 9x = -34x + 60, along with the properties used at each step:
Given equation: 2(10 - 13x) + 9x = -34x + 60
Step 1: Distribute the 2 on the left side of the equation.
Property used: Distributive Property
2 * 10 - 2 * 13x + 9x = -34x + 60
20 - 26x + 9x = -34x + 60
Step 2: Combine like terms on both sides of the equation.
Property used: Combining like terms
-26x + 9x = -34x + 60
(-26x + 9x) = (-34x + 60)
-17x = -34x + 60
Step 3: Add 34x to both sides of the equation to isolate the variable x on the right side.
Property used: Adding the same value to both sides of an equation to maintain equality.
-17x + 34x = -34x + 60 + 34x
17x = 60
Step 4: Finally, divide both sides by 17 to solve for x.
Property used: Dividing both sides of the equation by the same nonzero value to maintain equality.
(17x) / 17 = 60 / 17
x = 60 / 17
So, the solution to the equation is:
x = 60 / 17
Each step in this solution is justified by the properties of equality and arithmetic operations.
The complete question is here:
Justify each step of the solution by stating the property that was used to get to each step. Given: 2 (10-13x) + 9x = -34x + 60 Step 1: 20 - 26x + 9x = -34x + 60 Step 2: -17x = -34x + 10 Step 3: 17x = 40 Step 4: x =( 40)/(17) 40 on top of 17 as a fraction.

A container holds 16 pints of lemonade. how much is this in gallons?
Answers
Answer: 2 gallons of lemonade.
Step-by-step explanation:
The container holds 16 pints of lemonade, and we know that a pint corresponds to 0.125 gallons.
So 16 pints are equal to 16 times 0.125 gallons:
16*0.125 gallons = 2 gallons
Then the container holds 2 gallons of lemonade.

what are the base seven counting numbers just before and after 16 base seven ? ...?
Answers
Final answer:
In base seven, the number just before 16 is 15, and the number just after 16 is 20. These correspond to 5 and 14 in decimal notation, respectively.
Explanation:
The question asks for the base seven counting numbers just before and after 16 in base seven. In base seven, counting is similar to decimal but stops at 6 before moving to the next place value. The number 16 in base seven is written as 6 in base 10, since base seven does not have a digit for '7' or higher. Therefore, the counting sequence in base seven goes ...14, 15, 16, 20, 21... Thus, the number just before 16 in base seven is 15 (which is 5 in base 10), and the number just after 16 in base seven is 20 (which represents 14 in base 10).
A tangent-tangent angle intercepts two arcs that measure 135 degrees and 225 degrees. What is the measure of the tangent tangent angle?
Answers
Answer:
[tex]M=45 degrees[/tex]
Step-by-step explanation:
It is given that A tangent-tangent angle intercepts two arcs that measure 135 degrees and 225 degrees, thus in this the vertex lies outside, therefore
The measure of the tangent tangent angle is the half of the difference of the two given arc, that is
[tex]M=\frac{1}{2}(225-135)[/tex]
⇒[tex]M=\frac{90}{2}[/tex]
⇒[tex]M=45 degrees[/tex]
Therefore, The measure of the tangent tangent angle is 45 degrees.
What is the greatest factor of: 6x^2y^3 + 18x^3y^3 + 36x^3y^2
Answers
The greatest factor of the given expression is 6x^2y^2, found by identifying the common variables with the lowest exponents and the greatest common divisor of the coefficients.
Explanation:The student is asking to find the greatest common factor (GCF) of the algebraic expression 6x^2y^3 + 18x^3y^3 + 36x^3y^2. To find the GCF, we look for the highest exponents of the variables that are common in each term, and the largest coefficient that can evenly divide all the coefficients of the terms.
Firstly, we notice that each coefficient (6, 18, 36) is divisible by 6, so 6 is part of our GCF. Next, we see that the smallest exponent of x is 2 and the smallest exponent of y is 2 as well. So, x^2 and y^2 are also part of our GCF. The greatest factor is then 6x^2y^2.
Therefore, when we factor out the GCF from the expression, it would be written as:
6x^2y^2 (y + 3x + 6xy)
