Find the surface area of the rectangular prism please help

82

Step-by-step explanation:

surface area=pxh+2xb

p=perimeter of base

h=height

b=area of base

Perimeter of base=7+7+2+2=18

height=3

area of base=7x2=14

Surface area=18x3+2x14

surface area=54+28

surface area=82

5x+10 is the correct one

hope this

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
