User: Tom has a collection of 30 CDs and Nita has a collection of 18 CDs. Tom is adding 1 CD a month to his collection while Nita is adding 5 CDs a month to her collection. Find the number of months after which they will have the same number of CDs.
Weegy: Tom has a collection of 30 CD's and Nita has a collection of 18 CD's. Tom is adding 1 CD a month to his collection while Nita is adding 5 CD's a month to her collection. [ The number of months after which they will have the same number of CD's is: 3 months
***30 + x = 18 + 5x
x - 5x = 18 - 30
-4x = -12
x = -12/-4
x = 3

User: The area of a rectangle is x2 - 2x - 15 and the length of the rectangle is x + 3. Find the width of the rectangle.
A. x – 5
B. x2 + 15
C. x + 5
D. (x – 2)(x + 3)
Weegy: Hi
Area = length * width
x^2-2x-15=(x+3)*width
we can write area in terms of (x-5)*(x+3)=(x+3)*width
so width is A. x ? 5
