Answer:
x+4
Step-by-step explanation:
x² + 8x² +16 = x² + 2*4x +4² = (x+4)²
Area of a square = side²
So, the length of one side of the given square is (x+4).
The expression that represent the length of one side of the square is x+4.
Calculation of the expression:Since the equation is
[tex]= x^2 + 8x^2 +16[/tex]
So, we can write as the
[tex]= x^2 + 2\times 4x +4^2 \\\\= (x+4)^2[/tex]
Now we know that
Area of a square = side²
hence, we can say that the expression that represent the length of one side of the square is x+4.

Which graph represents the equation y = --3x – 1?
Answer:
Step-by-step explanation:
The equation y = -3x - 1 represents a straight line with a slope of -3 and y-intercept of -1. The graph will be a line falling to the right and crossing the y-axis at -1.
Explanation:The question asks which graph represents the equation y = -3x - 1. This is a linear equation, where the coefficient of 'x', -3 here, gives us the slope of the line, and the constant, -1 here, gives us the y-intercept. A slope of -3 means for each step of 1 increase in x, the value of y decreases by 3. The y-intercept is the point where the line intersects with the y-axis, in this case at y = -1.
A graph representing this equation will be a straight line with a slope of -3 (indicating the line falls as we move along the positive x-axis) and will cut the y-axis at y = -1.

Step-by-step explanation:
Kylie went on a road trip with her family. They traveled at an average speed of 50 miles per hour for 2.5 hours and then traveled at an average speed of 65 miles per hour for 3 hours. What was the total distance in miles that Kylie’s family traveled during this time?
Answer: 320 miles
Step-by-step explanation:
First, we need to make an equation. However, we can’t fight to label the variables:
t = total number of miles
h = number of hours
Now let’s set up our equation:
t = 50h + 65h
The good thing is that we know how many hours each speed was held for, so we can substitute it in the equation.
t = 50(2.5) + 65(3)
t = 125 + 195
t = 320
Therefore, the total number of miles traveled is 320.
The total distance in miles that Kylie’s family traveled during this time is 320 miles.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that Kylie traveled at an average speed of 50 miles per hour for 2.5 hours and then traveled at an average speed of 65 miles per hour for 3 hours.
First, we need to make an equation thus we have;
t = total number of miles
h = number of hours
Now let’s set up our equation as;
t = 50h + 65h
Now we can substitute it in the equation.
t = 50(2.5) + 65(3)
t = 125 + 195
t = 320
Therefore, the total number of miles traveled is; 320 miles.

A motorboat travels 9 miles downstream (with the current) in 30 minutes. The return trip upstream (against the current) takes 90 minutesWhich system of equations can be used to find x, the speed of the boat in miles per hour, and y, the speed of the current in miles per hour? Recall the formula d = rt..
Answer:
Option B
Step-by-step explanation:
When moving with the current, the speeds of the boat and current will add up. The first situation can then be represented by:
9 = 0.5(x + y)
While opposing the current, the speeds will be subtracted. Forming:
9 = 1.5(x - y)
The second option contains this equation system, so it is correct.

Quincy folds a piece of cardboard to make the three sides of a triangular prism open at top
and bottom. The triangular prism and the piece of cardboard that he used are shown below.
What is the area of the piece of cardboard?
Answer:
500 cm2
Step-by-step explanation:
The dimensions of the prism are 7 cm, 9 cm and 20 cm.
So the three areas we want to find are three rectangles, with the sides:
7 cm and 20 cm, 9 cm and 20 cm, 9 cm and 20 cm
The area of each rectangle is:
rectangle_1 = 7 * 20 = 140 cm2
rectangle_2 = 9 * 20 = 180 cm2
rectangle_3 = 9 * 20 = 180 cm2
Summing all these three areas, we have:
Total area = 140 + 180 + 180 = 500 cm2

What is the approximate population density (people per square kilometer) of Australia/Oceania? Write your answer in standard form. If necessary, round your answer to the nearest hundredth.
Answer: 3.11*10^7/7.69*10^63110/769 Answer:4.04
will I still get brainliest?
The population density of Australia/Oceania is calculated by dividing the total population (3.11 × 107 people) by the total area (7.69 × 106 square kilometers), which results in a density of approximately 4.04 people per square kilometer.
Explanation:To calculate the population density of Australia/Oceania, we need to divide the total population by the total area. The area of Australia/Oceania is approximately 7.69 × 106 square kilometers, and the population is approximately 3.11 × 107 people.
The calculation for population density is:
Population Density = Total Population / Total Area
So:
Population Density = 3.11 × 107 people / 7.69 × 106 square kilometers
This results in a population density of
Population Density = 4.04363 people per square kilometer (unrounded)
Rounded to the nearest hundredth, the population density is approximately 4.04 people per square kilometer.

One side of a rectangle is three times the other. Find the longer side if the perimeter is
29
Answer:
Answer: 10.875
Step-by-step explanation:
Let the short side be x.
Then the long side is 3x.
There are two opposite sides of each length, so the perimeter is
3x + 3x + x + x = 8x
The perimeter is 29, so we get the equation
8x = 29
Solve for x by dividing both sides by 8.
x = 29/8
x = 3.625
The longer side is 3x.
3x = 3(3.625) = 10.875
Answer: 10.875
Answer:
Answer:10.875
Step-by-step explanation:
Let the short side be x.
Then the long side is 3x.
There are two opposite sides of each length, so the perimeter is
3x + 3x + x + x = 8x
The perimeter is 29, so we get the equation
8x = 29
Solve for x by dividing both sides by 8.
x = 29/8
x = 3.625
The longer side is 3x.
3x = 3(3.625) = 10.875

longer than it is wide. If the afghan has an
area of 24 square feet, what is its width?
(Remember, the area of a rectangle is its
length times its width.)
Answer:
The width is 4
Step-by-step explanation:
If the length is 6 feet, minus 2 will be 4. Six times 4 is 24, which is the area of the afghan rug. We are multiplying 6 and 4 because it is length times width in rectangle area.
Mrs. Henson's rectangular afghan width will be 4 feet
