The area of the rectangle and square are equal find x.

10 =x

Step-by-step explanation:

The area of the square is

A = s^2 where s is the side length

A = 6^2 = 36

The area of the rectangle is

A = l*w

A = 3(x+2) = 3x+6

We know the areas are equal

36 = 3x+6

Subtract 6 from each side

36-6 = 3x+6-6

30 = 3x

Divide by 3

30/3 = 3x/3

10 =x

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
