Question

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

Answer 1

F5) + G(6) = 59

Explanation:

It is given that, F(x) = x² + 4x and G(x) = 2x + 2

To find the value of F(5) + G(6)

F(x) = x² + 4x

F(5) = 5² + (4 * 5)

= 25 + 20

= 45

G(x) = 2x + 2

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

= 12 + 2

= 14

F5) + G(6) = 45 + 14 = 59

Answer 2

59.

Explanation:

F(x) = x² + 4x (Equation 1).

G(x) = 2x + 2 (Equation 2).

In this simple questions, two function values have to be added. Put x = 5 in Equation 1 and x = 6 in Equation 2.

F(5) = (5)^2 + 4*(5) = 25 + 20 = 45.

G(6) = 2*(6) + 2 = 12 + 2 = 14.

Therefore, F(5) + G(6) = 45 + 14 = 59.

Therefore, 59 is the correct answer!!!
