Answer:

9+10x

Step-by-step explanation:

Given: g(x)= -3x2 + 5x = -6+5x

    and h(x) = 2x +1

Find: g(h(x+1))

1!

h(x+1)= 2(x+1) +1

        =2x+3

2! substitute h(x+1)in function g(x)

g(h(x+1))= -6 + 5(2x+3)

             = -6+10x+15

             = 9+10x

ps. im not sure (-3x2 + 5x) is -6+5x (-3 multiply 2) or question is not clear

<h3>What is algebraic expression?</h3>

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Amelia is using substitution to determine if 8 is a solution to the equation.  The equation which is Amelia is solving  for a = 8 is,

6a = 42

First, Amelia must substitute 8 for the variable using parentheses as,

6(8) = 42

To simplify, Amelia must. multiply 8 by 6.

48 \neq 42

The left hand side of the eqqation is not equal to the right hand side. Thus, 8 is not a solution of the equation.

Thus, Amelia must substitute 8 for the variable using parentheses. To simplify, Amelia must multiply 8 by 6. 8 is not a solution of the equation.
