Twice the difference of x and 5

Novosadov [1.4K]

Answer:

2*(x-5) = -33, so x-5 = -16.5, so x = -11.5

What is the surface area of the square pyramid represented by the net? Enter your answer in the box. m² An unfolded square base

OlgaM077 [116]

Answer:

The surface area of the square pyramid is $144\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to

$SA=B+Ph/2$

where

B is the area of the base

P is the perimeter of the base

h is the height of the pyramid

$B=6^{2}=36\ m^{2}$

<u>Find the perimeter of the base P</u>

$P=4*6=24\ m$

The height is $h=9\ m$

substitute the values

$SA=36+24*9/2=144\ m^{2}$
