Answer:
No, because the 3 angles of a triangle must add up to 180 degrees and yours only add up to 55
Step-by-step explanation:
F(f-1x) will be equal to x
take a simple example
f(x) = 2x
so x = f(x) / 2
f-1(x) = x/2
f(f-1x) = 2 ( x/2) = 2 * x/2 = x
Answer:
5xy
Step-by-step explanation:
x and y can only go into both into once
