Answer:
The answer is b
Step-by-step explanation:
(4x+5)(16^2-20x+25)
<h2>
AREA</h2>
The formula for finding area of a square is:

In a square, all the sides are the same. Each side is 6 meters long. Plug in 6 to the formula.

Multiply:

The area of the square is 36 m²
<h2>PERIMETER</h2>
Perimeter is the distance around a shape. To find perimeter, you have to add all all the side lengths. The formula for finding perimeter is:

Remember that squares have 4 sides, and all length(s) and width(s) measure the same. The length and width measure the same. Plug in the numbers into the formula:

Simplify:

Add:

The perimeter of the square is 24 m
Part A: 5 is the coefficient, w is the variable, 50 is the constant
Part B: 10 x 5 = 50 + 2 x 20 = 40+ 50 = $140
Part C: the constant,50,would change and become 85. Hope this helps :)
Circle A would make more sense (I'm not exactly sure) because it shows the entire circle (if you know what I mean).
The perimeter of a square is the sum of all its sides' lengths
That means: perimeter =4*(7m+1)/3
