Answer:

q = 7

Step-by-step explanation:

Given

18 - 2q = 4 ( Isolate the term in q by subtracting 18 from both sides )

- 2q = - 14 ( divide both sides by - 2 )

q = $\frac{-14}{-2}$ = 7

What is the total surface area of the rectangular pyramid whose net is shown?

Lunna [17]

Answer:

95 in.²

Step-by-step explanation:

Total surface area of the rectangular pyramid = 4(area of triangle) + area of rectangle

Area of triangle = ½*base*height

base = 5 in.

height = 7 in.

Area of triangle = ½*5*7 = 17.5 in.²

Area of rectangle = Length*width = 5*5 = 25 in.²

Plug in the values

Total surface area of the rectangular pyramid = 4(17.5) + 25

= 95 in.²
