5y + 4 = 5(y + 5) – 21
~Simpify right side
5y + 4 = 5y + 25 - 21
5y + 4 = 5y + 4

5y = 5y
~Divide 5 to both sides
0 = 0

Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces
so
![SA=b^{2}+4[\frac{1}{2}(b)(l)]](https://tex.z-dn.net/?f=SA%3Db%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28l%29%5D)
where

-----> the slant height
substitute the values
![SA=9^{2}+4[\frac{1}{2}(9)(12)]](https://tex.z-dn.net/?f=SA%3D9%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%289%29%2812%29%5D)
