If f(x) = 2x^2 + 3x and g(x) = x - 2, what is (f + g)(2) ?

(f + g)(2)=14

Step-by-step explanation:

If f(x) = 2x^2 + 3x

g(x) = x - 2

(f + g)(2)

Lets find

(f+g) (x)

We add the 2 functions

(f+g) (x)=2x^2 + 3x + x - 2

Combine like terms

(f+g) (x)=2x^2 + 4x - 2

Now we let x=2

(f+g) (2)=2(2)^2 + 4(2) - 2

(f+g) (2)=2(4) + 8 - 2

            =8+8-2

               =14

3x + 4x + 5x = 156

12x = 156

x = 13

3*13 = 39

5*13 = 65

65-39=26 cm difference
