Basically expand
use FOIL (a way to remember distributive property)
first outer inner last
that is th eorder to multiply them
First: x times 2x=2x²
Outer: x tmes 9=9x
Inner: -8 times 2=-16x
last: -8 times 9=-72
add them
2x²+9x-16x-72
2x²-7x-72
Answer:Step-by-step explanation:
All. They all add up to 40.
Answer:
The remainder is -9
So, Option A is correct.
Step-by-step explanation:
We need to divide the polynomial 
by 
and determine the remainder.
The division is shown in the figure attached.
The remainder is -9
So, Option A is correct.
40÷5= 8 You have to see how many time 5 can go into 40
1. see how many times 5 goes into 4 none so the first number is 0
2. then you see how many time 5 can go into 0 o times
3. so you have to see how many time you can count 5 into 40
(count by 5's) 5,10,15,20,25,30,35,40 that should be 8 times total!
