If the perimeter is 20 what must be the length of the missing side length? (Answer with Number Only) *

8

Step-by-step explanation:

Perimeter = Sum of all side lengths

If perimeter = 20, then 5 + 3 + 4 + x = 20

( where x = missing side length )

5 + 3 + 4  = 12

12 + x = 20

20 - 12 = 8

Hence, x = 8

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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)
