Answer:
85
Step-by-step explanation:
10x13=130, 9x5=45, 130-45=85
Width=1cm and length=21cm or width=3cm and length=7cm.
The equation with (x) in dogs and (y) in dollars is 
First, you must set up your equation.
Then, you must add like terms to simplify the equation
To find the 3rd side of a triangle, use the pythagorean theorem.
a^2 + b^2 = c^2
a = 11
b = ?
c = 23
11^2 + b^2 = 23^2
121 + b^2 = 529
b^2 = 408
b = √408 = 2 √102 = 20.199, 20.2, or 20
The answer can be any of those.
The answer to the first part of your question is 9
as for the second part 36/4 (which is 9 btw) then subtract 2 I answered this one the best I could (let me know if I'm wrong)
(i just don't have to much time on my hands because I have homework myself)
