the answer would be C because 7(-1) -5(-7) would be -7+35 which equals 28
Answer:
270 ft³
Step-by-step explanation:
1/2x9x6x10=270
The equation to find a spheres surface area is 4 pi R ^2
and this works in any order
4 * 12 is 48 (4 * R)
48^2 is 2304 ((4 * R)^2)
the exact answer is 2304

the full answer is 7234.56 (((4 * R)^2)

)
Add 4x
to both sides of the equation.
a. y=4x+6
Add 5x to both sides of the equation.
b. y=5x+21
The answer would be B simply because it sounds more reasonable.
