Answer:
B. x3 + 4x2 − x + 3
Step-by-step explanation:
(−7x^3 + 5x^2 − x + 6) − (−8x^3 + x^2 + 3)
Distribute the negative sign
(−7x^3 + 5x^2 − x + 6) + (8x^3 - x^2 - 3)
I like to line them up vertically.
−7x^3 + 5x^2 − x + 6
8x^3 - x^2 - 3
----------------------------------
x^3 +4x^2 -x +3
Answer:
20%
Step-by-step explanation:
To find out the percent decrease of the price of the lotion, the first step is to get the amount of the decrease in price.
The lotion is normally $3.00 for the bottle.
This week, it's at $2.40 for the same bottle.
The difference is then of $0.60 per bottle.
Now, we take that $0.60 and we divide it by the original price of $3, we get:
$0.60 / $3.00 = 0.20
So the special is a reduction of 20% from the original price of $3.00 per bottle.

Sour patch = 
As a percentage , multiply 1/16 by 100 and it becomes 6.25%
Answer:
Add 3x to both sides
Step-by-step explanation:
after you add 3x you get 11=3x+44
next you subtract 44 from each side
you then get -33=3x then you divide by 3 on both sides and your final answer is x= -11
