=Answer:
Step-by-step explanation:
f(-7) = -(-7)^2 - 10(-7) = -49 +70 = 21
You need to find surface area for this
so the answer is 164in^2
Answer:
O C.
Step-by-step explanation:
To find a missing side length, use Pythagorean Theorem:
a^2 + b^2 = c^2 where a = 5 b = x and c = 6
5^2 + x^2 = 6^2
25 + x^2 = 36
x^2 = 36 - 25
x^2 = 11
x = 3.3
The value of x is sqrt rt 11
