If A = -3n + 2, and B = 5n - 7, what is the value of A + B, in simplest form? 2n + 9
-8n - 5
-3n
2n - 5

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
