Which of the following is a factor of f(x) = 3x3 + 8x2 − 87x + 28? (5 points) (x − 1 over 4 ) (x + 1 over 4 ) (x − 4) (x + 4)

Answer

(x - 4)

Step by step explanation

To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.

Here (x - 4) is a factor.

Therefore, x = 4

when we plug in x = 4 in the given expression, we get zero.

Let's check it out.

3(4)^3 + 8 (4)^2 - 87(4) + 28

192 + 128 - 348 + 28

348 - 348

0

The answer is (x - 4)

Thank you.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
