Answer:
x² + 9x + 20
Step-by-step explanation:
Area of a rectangle can be found by multiplying the base with height (or length with width).
A(r) = l x h.
Multiply. Plug in:
x + 5 for l
x + 4 for h
A(r) = (x +5) * (x + 4)
Use the FOIL method to solve. Multiply the first terms of both parenthesis, the outside terms, the inside terms, and then the last terms. Combine like terms:
A(r) = (x + 5) * (x + 4)
x * x = x²
x * 4 = 4x
5 * x = 5x
4 * 5 = 20
x² + 4x + 5x + 20
x² + (4x + 5x) + 20
x² + 9x + 20
x² + 9x + 20 is your answer.

J'K'L'M'N', I believe. Unless there is a graph you'd like to link
(x+3)/3 = (y+2)/2
Note: please add parentheses so you don't cause confusion. x+3/3 is totally different from (x+3)/3
2(x+3) = 3(y+2)
2x+6 = 3y+6
2x=3y
x = 3y/2
x/3 = (3y/2)/3 = y/2
Yes, that is correct.
If you took everything apart, -m is actually -1*m. mn=m*n
