If f(x) = 2x-5 and g(x) = x2 - 4x - 8, find (f+ g)(x). O A. (f+9)(x) = x2 - 2x - 13
O B. (f+g)(x) = x2 + 2x - 3
O C. (f+g)(x) = x2 - 2x-3
O D. (f+g)(x) = 3x2 - 4x - 13

A. (f+g)(x)= -2x-13

Step-by-step explanation:

Add f(x) and g(x)

= (2x-5)+(-4x-8)

Add like terms.

=-2x-13

(f+g)(x)= -2x-13

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
