PLEASE LOOK at the photo and help me on these 2 questions :(!!!!!
Tems11 [23]

Answer:

1) f(g(2)) = 24

2) f(g(-1)) = -4

Step-by-step explanation:

1) GIven f(x) = x²+2x and g(x) = 2x

f(g(x)) = f(2x)

f(2x) = (2x)² + 2(2x)

f(2x) = 4x² + 4x

f(g(x)) = 4x² + 4x

f(g(2)) = 4(2)² + 4(2)

f(g(2)) = 16+8

f(g(2)) = 24

2) f(x) = x+1 and g(x) = 5x

f(g(x)) = f(5x)

f(5x)= 5x + 1

f(g(x)) = 5x + 1

f(g(-1)) = 5(-1) + 1

f(g(-1)) = -5+1

f(g(-1)) = -4

What is the difference of the polynomials [m²n²-7]-(mn+4)
AleksAgata [21]
You can do addition and substraction operations with polynomials similarly as with simple real numbers.


First of all you have to open brackets and then you can add numbers (-7-4=-11). Then the result is following:
(m^2n^2-7)-(mn+4) =m^2n^2-7-mn-4=m^2n^2-mn-11
