A: is 14
B: is 10-14=-4
C:-27+-15=-42
-42+100=58.
Answer:
i am goin to say C
Step-by-step explanation:
The formula is pi times the radius squared
Factor:
9x^2 - 64
= (3x)^2 - 8^2
= (3x + 8)(3x - 8)
If you want to solve it, let the equation equal zero
(3x + 8)(3x - 8) = 0
3x + 8 = 0 ; x = -8/3
3x - 8 = 0 ; x = 8/3
Solutions: x = -8/3 and x = 8/3
