Answer:
Step-by-step explanation:
Approximate the integral
by dividing the region
with vertices (0,0),(4,0),(4,2) and (0,2) into eight equal squares.
Find the sum 
Since all are equal squares, so
for every 

Thus, 
Evaluating the iterate integral ![\int\limits^4_0 \int\limits^2_0 {(x+y)} \, dydx=\int\limits^4_0 {[xy+\frac{y^2}{2} ]}\limits^2_0 \, dx =\int\limits^4_0 {[2x+2]}dx\\\\=[x^2+2x]\limits^4_0=24.](https://tex.z-dn.net/?f=%5Cint%5Climits%5E4_0%20%5Cint%5Climits%5E2_0%20%7B%28x%2By%29%7D%20%5C%2C%20dydx%3D%5Cint%5Climits%5E4_0%20%7B%5Bxy%2B%5Cfrac%7By%5E2%7D%7B2%7D%20%5D%7D%5Climits%5E2_0%20%5C%2C%20dx%20%3D%5Cint%5Climits%5E4_0%20%7B%5B2x%2B2%5D%7Ddx%5C%5C%5C%5C%3D%5Bx%5E2%2B2x%5D%5Climits%5E4_0%3D24.)

Answer:
ANYTHING! MY EXAMPLE - 24x7
Step-by-step explanation:
First, I would like to find out the length of Paula"s painting.
168/12 = 14
So, Paula's dimensions are 12x14
Since we have the area, we could easily just divide 168 by anything.
168/24 = 7
So, Juan's dimensions could be 24x7 (hey that's funny, 24-7?)
Hope this helps!

Answer:
The mean is 40.5
Step-by-step explanation:
Answer:
6. 4x^2 + x - 1
7. 3x^2 + 4x + 4
Explanation:
(3x^2 + x + 8) + (x^2 - 9)
4x^2 + x - 1
(5x^2 + 8x - 2) - (2x^2 - 4x + 6)
3x^2 + 4x + 4
