Question

If F(x) = x² + 4x and G(x) = 2x + 2, find F(5) + G(6).

Answer 1

i got 59 on my test and it was correct

Answer 2

59

Explanation:

We are given that

`F(x)=x^2+4x`

`G(x)=2x+2`

We have to find the value of F(5)+G(6).

Substitute x=5 in F(x)

`F(5)=(5)^2+4(5)=45`

Substitute x=6 in G(x)

`G(6)=2(6)+2=14`

`F(5)+G(6)=45+14=59`

Answer: 59
