Answer:
-12x^2 + 11xy - 2y^2
Step-by-step explanation:
If you want the answer youse a calculator or do 21 divided by 38
Simplify means solve and to solve we first need to do 2 to the 2nd power which is two * 2 that equal 4 than do 2 to the 10th power that equal 1024 and than we can just do
4 divided by 1024 = 0.0390625
1) Would be c+15 because you can combine 19-4
2) Would be m+2 because you can combine 12-10
Let X = tree height.
X/146 = 5.6/11.2
