Simplify the product. Write the answer in standard form.
(x2 + 4)(x+3)

x^3 + 3x^2 + 4x + 12

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
