Alice wants to find the area of a rectangular sandbox. The length of the sandbox is 3x3 + 62 - 2
and the width is 2.2 - 4
"Label each answer as shown below*
A. What is the area? *** remember to use to show exponent (shift
6) Please don't be spaces in between the signs
B. Classification Terms
C. Degree
D. All coefficients (separated by commas)-
E. Leading coefficient-

step-by-step explanation:

the answer is 128

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

its adding 5.5 each time
