Which equation, when graphed, has x-intercepts at (8,0) and (-2,0) and a y-intercept at (0, -48)? f(x) = -3(x - 3)(x + 2)
f(x) = -3(x + 8)(x - 2)
f(x) = 3(x - 3)(x + 2)
f(x) = 3(x + 3)(x - 2)

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

step-by-step explanation:

answer: the answer is ann

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
