Which of the following is a solution of x2 - 7x = -5?

answer:

x = 1

step-by-step explanation:

trial and error:

let's say that x is 1. (2*1) = 2, and (7*1) = 7. 2 - 7 = -5. therefore, x = 1.

also, you didn't show the "of the following"

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate
