The Perimeter of the school crossing sign is 102 inches. What is the length of each side?

s = 15 inches

2s = 30 inches

s + 6 = 21 inches

Step-by-step explanation:

The top ones are 21 inches, the sides are 15 inches, and the bottom one is 30 inches.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
