Answer:
A. 675 units²
Step-by-step explanation:
The formula for the surface area of a square pyramid is ...
A = s(s +2h)
where s is the side length of the base, and h is the slant height of a face.
__
<h3>use the formula</h3>
The given pyramid has s=15 and h=15, so the surface area is ...
A = (15)(15 +2×15) = 15(45) = 675 . . . square units
Answer:
for what lol
Step-by-step explanation:
Answer: 5mn + 5m + 4n + 4
because
2mn - 7mn = 5mn
5m = 5m
stays the same
4n = 4n
stays the same
2 + 2 = 4
if you put them toghether than you get:
5mn + 5m + 4n + 4
is equal to
2mn + 4n + 2 and 5m + 2 -7mn

Substitute 16 for a
16-4
Subtract
Final Answer: 12</span>
