<span>4x(5y-x)-5y(4x-y)=20xy-4x^2-20yx+5y^2=-4x^2+5y^2=5y^2-4x^2</span>
1) pythagorean theorem = a2 + b2 = c2
SO:
10^2 + 6^2 = c2
100 + 36 = c2
136 = c2
Diagonal should equal about 11.66 meters
2) pythagorean theorem = a2 + b2 = c2
SO:12.7^2 + 8.9^2 = c2
161.29 + 79.21 = c2
240.5 = c2
Elevation should equal about 15.1 degrees
I think it’s 1.3, if it’s not than I’m so sorry

Answer:
A. 33x + 92y
Step-by-step explanation:
Set up the problem like this and combine like terms:
40x + 58y
- 7x + 34y
--------------------
33x + 92y
Or, set up the problem like this and combine like terms:
(40x + 58y) + (-7x + 34y)
40x + 58y - 7x + 34y
40x - 7x + 58y + 34y
33x + 92y
You should get the same answer with either method.
