# Given that S^3 on the bottom 1 (e^x)dx=(e^3)-e use the properties of integrals and this result to evaluate S^3 on the bottom 1 (5e^x − 1) dx. I got 5e^3x-5e-1 is this correct? Please help!

1) For functions and ,
2) For a function and a constant ,

Using these two properties of integrals, and the fact that , we can see that

The length of a rectangle is 7 more than its width. The area of the rectangle is 120. Solve for the length and the width.

Length times width times height
L = w + 7
W = w
A = L * W
120 = w(w+7)
120 = w^2 + 7w
Subtract 120 from both sides.
w^2 + 7w - 120 = 0
Factor
(w + 15)(w - 8) = 0
Set each factor equal to zero.
w = -15, w= 8
Cannot be -15 so w = 8
Length = 15
Width = 8
