Answer:
126°
Step-by-step explanation:
(2x +18)° = (3x)°

18 = 3x - 2x
18 = x
therefore, (3x)° = (3*18)°= (54)°

Answer:
Rate of Change is 1
Step-by-step explanation:
The Average rate of change is the ratio of change in y and the change in x
Hence
Avg Rate of Change = Change in y / Change in x
The two coordinates are
(-4,0) and (0,4)
Change in x = 0-(-4) = 4
Change in y = 4-0 = 4
Hence
Avg Rate of Change = 4/4
= 1

The area of a square is

where
b is the length side of the square
we have

substitute in the formula and solve for b

square root both sides

To determine the total length of wood , calculate the perimeter of the sandbox
