Y 50 I think it is I am not to sure
First equation
L.H.S = 4x -0.25y
so it doesn't equal the R.H.S
2nd equation
R.H.S = 15q + 3qr
so it doesn't equal the L.H.S
3rd equation
R.H.S = -30m -60n
so R.H.S doesn't equal L.H.S
4th equation
L.H.S = -16a +4
so L.H.S equal R.H.S

f(g(x)) = x^4 + 2x^3 - x
g(f(x)) = x^4 + 2x^3 + 2x^2 - x
Step-by-step explanation:
f(x) = x^2 - x ; g(x) = x^2 + x
f(g(x)) = (x^2 + x)^2 - (x^2 + x)
f(g(x)) = (x^2 + x)^2 - x^2 - x
f(g(x)) = (x^2 + x)(x^2 + x) - x^2 - x
f(g(x)) = x^4 + x^3 + x^3 + x^2 - x^2 - x
f(g(x)) = x^4 + 2x^3 - x
g(f(x)) = (x^2 - x)^2 + x^2 - x
g(f(x)) = (x^2 + x)(x^2 + x) + x^2 - x
g(f(x)) = x^4 + x^3 + x^3 + x^2 + x^2 - x
g(f(x)) = x^4 + 2x^3 + 2x^2 - x
