Ineed with this i don’t know how many terms there are.

A:

So terms are a group of numbers/variables or a single number/variable. They are separated by + and - symbols.

In the original equation, there are 6 terms: 5x^2, 6x, -3, 4x^2, -8x, and 2.

To find the simplified equation, just combine like terms, which in this case are (5x^2 + 4x^2) + (6x - 8x) + (-3 + 2).

Simplify that, and your simplified equation is 9x^2 - 2x - 1 . And within this simplified equation, there are 3 terms: 9x^2, -2x, and -1.

B:

Going back to A, we see that our simplified expression is 9x^2 - 2x - 1 . Looking at our equation, the coefficient of x is -2.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

hi how are you doing today? if you ever need just tell me
