Help is greatly needed. I can’t figure this stuff out

6x^3 +4x^2+4x-8 so D.

Step-by-step explanation:

Hey, this problem may look difficult but it is actually pretty easy. The (f-g)(x) is a tricky way of saying f(x)-g(x). So:

(2x^2 +4x-5)-(6x^3 -2x^2 +3)

First you distribute the negative sign

2x^2+4x-5-6x^3 +2x^2 -3

Then combine like terms

2x^2 + 2x^2 = 4x^2

6x^3 (Stays constant due to no like terms)

4x (Also stays constant due to no like terms)

-5-3= -8

So d.

Hope this helps

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
