If g(x) = - 2x² - 5x + 7, then what is the value of g(-2)?

16 + 10 + 7, which equals 33

Step-by-step explanation:

g(-2) means you need to replace all x's in the equation with -2. So the equation becomes:

-2(-2)^2 - 5(-2) + 7, which equals 16 + 10 + 7, which equals 33

Hope this helps!

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
