The best way to find x is knowing the different angles and their properties and theorems.
Perimeter=sum of all 3 sides
Answer:
10x^3+14x^2-25x-35
Step-by-step explanation:
f(x) = 2x^2 -5
g(x)= 5x+7
f(g(x)) = (2x^2 -5)(5x+7)
5x(2x^2 -5)+7(2x^2 -5)
10x^3-25x+14x^2-35
10x^3+14x^2-25x-35
Step-by-step explanation:
A,true
doesn't interfere with any function restriction
The additive inverse of something is whats added to the original to get 0
So in this case n - n = 0, which is B :)
