Question

If F(x)=x^3+5x and G(x) =2x+1, find F(5) + G(6)​

Answer 1

Answer:

$F(5)+G(6)=163$

Step-by-step explanation:

We were given that:

$F(x)=x^3+5x$ and $G(x)=2x+1$

When x=5

$F(5)=5^3+5*5$

$F(5)=125+25=150$

When x=6

$G(6)=2*6+1$

$G(6)=12+1=13$

This implies that:

$F(5)+G(6)=150+13=163$
