the area of a rectangle is represented by the function x3 + 11x2 + 3x − 135. the width of the rectangle is x − 3. find the expression representing the length of the rectangle.
a. x^2 − x − 30
b. x^2 + 14x + 45
c. x^2 + 11x + 30
d. x^2 − 4x − 45

B. x^2 + 14x + 45.

Step-by-step explanation:

Length = area / width so we do a

Long division:

x - 3) x3 + 11x2 + 3x − 135(x^2 + 14x + 45 < Quotient.

        x3 - 3x2

               14x^2 + 3x

               14x^2 - 42x

                            45x - 135

                            45x - 135.

c

step-by-step explanation:

c

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
