3 & -3 are 3 units from zero
Original height = original width = x mm
1. She made an enlarged copy...
height = 2x
width = 2x
2. She cut off a rectangle...
height = 2x
width =

3.She doubled the width...
height = 2x
width =

height * width = area

Original height was
162 mm
190/5 = 38
So, they can make 38 quarts in an hour.
38 * 36 = 1,368
They can make 1,368 quarts in 36 hours.
From the following choices, the correct step in evaluating: ∫ cos2 5x dx is 1 - cos 10x / 2dx.
For this case we must find an expression equivalent to:

We look for the factors of 10 and 30:
10: 1,2,5,10
30: 1,2,3,5,6,10,15,30
The greatest common factor of both numbers is 10.
Then, we can rewrite the expression as:

Answer:
