Answer quickly and ! will give
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.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

345
