If f(x)=4x3+3x2−5x+20 and g(x)=9x3−4x2+10x−55, what is (g−f)(x)?
Montano1993 [528]

Answer:

Step-by-step explanation:

(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]

To remove the parenthesis, take - inside, multiply f(x) by -1

= 9x³ - 4x² + 10x - 55 -  4x³ - 3x² + 5x - 20  

Now, bring like terms together,

= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20

= 5x³ - 7x² + 15x - 75

PLease school is almost over HELP 30x+60x=?
kolezko [41]

Answer:

90x

Step-by-step explanation:

30x+60x=?

If you want to solve this easily, you can just remove x and add 30x + 60x.

30+60

We know that 30 + 60 is 90. So we will add x to 90.

90x

Now you have your answer!

Hope this helps!
