Question

If F(x) = x² + 5x and G(x) = 2x + 1, find F(5) + G(6).

Answer 1

Answer:  The required value is 63.

Step-by-step explanation:  We are given two functions F(x) and G(x) as follows :

$F(x)=x^2+5x,\\\\G(x)=2x+1.$

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

We have

$F(5)=5^2+5\times5=25+25=50,\\\\G(6)=2\times6+1=12+1=13.$

Therefore, we get

$F(5)+G(6)=50+13=63.$

Thus, the required value is 63.

Answer 2

F(5) = 5² + 5(5) = 25 + 25 = 50
G(6) = 2(6) + 1 = 12 + 1 = 13 

F(5) + G(6) = 50 + 13 = 63

answer
F(5) + G(6) = 63
