inna [77]3 years ago
5 0

Answer:

A

B

D

Step-by-step explanation:

A 230 divided by 4 is 57.5 which makes A a true statement.

B 296 divided by 5 is 59.2 which makes B a true statement .

D 296 - 230 =66

66 - 57.5 = 8.5

Which makes D a true statement by a margin of 8.5 words.

The volume of a rectangular prism is 2x^3+9x^2-8x-36 with height x + 2. Using synthetic division, what is the area of the base?
navik [9.2K]

Answer:

Area of the base = 2x^2+5x-18

Step-by-step explanation:

We know that volume of rectangular prism = (Area of base) x (Height)

or [Area of base] = [Volume]/[Height]

So basically we need to divide given area by given height to find the answer.

given height is (x+2) that means (x+2) must be factor of volume equation

or x=-2 must be root of volume equation so write down coefficients of volume equation then we divide by -2 as shown in attached picture.

Last digit on the right is always remainder.

Remaining coefficients {2, 5, -18} will give the area equation: 2x^2+5x-18

Hence final answer is:

Area of the base = 2x^2+5x-18
