Distributive property or
use FOIL (FOIL is just an acronym to help you remember how to multiply binomials)

distributive property
a(b+c)=ab+ac
(b+c)a=ba+ca

distribute
(-3s+2t)(4s-t)=
(-3s+2t)(4s)+(-3s+2t)(-t)=
(-3s)(4s)+(2t)(4s)+(-3s)(-t)+(2t)(-t)=
-12s^2+8st+3st-2t^2=
-12s^2-2t^2+11st

if you want foil

FOIL (just tells wich terms to multiply)
First
Outer
Inner
Last

exmaple
with
(a+b)(c+d)
First: a times c
Outer: a times d
Inner: b times c
Last: b times d
then add them


(-3s+2t)(4s-t)
First: -3s times 4s=-12s^2
Inner: 2t times 4s=8st
Outer: -3s times -t=3st
Last: 2t times -t=-2t^2

add them
-12s^2+8st+3st-2t^2=
-12s^2+11st-2t^2

same

Need answer ASAP <br> *MARKING BRAINLIEST
NikAS [45]

Answer:

an = 4n +5

Step-by-step explanation:

First we need to find a common difference

d = a2-a1 = 13-9 = 4

The formula for an

an =a1+d(n-1)

an = 9 + 4(n-1)

Distributing

an = 9+4n-4

Combine like terms

an = 4n +5

What dose 5h-2+9h equal explain☺
DerKrebs [107]
Start out by combining LIKE TERMS 
5h-2+9h 
in this case 9h and 5h are like terms so you would add both of those together.
9h+5h=14h
-2 has no like terms so we can't do anything with it our final answer would be:
14h-2
