Answer:
We need to add the expression: 
Step-by-step explanation:
As the first step, add the first two polynomials listed in order to find what their sum is. Do such by combining like terms:
now, you need to find another polynomial (let's call it P(x)) such that added to the one we just found above, will render 
as a result.
Putting this phrase in mathematical terms, we write:
Now we solve for this unknown P(x) in this equation, by subtracting each of the terms that are accompanying it on the left side of the equation. We do one at a time for clarity:
Therefore, the expression we need to add is:
option B is the best it will only lead up to $1.92 while option A is a dollar more
Answer:
When factoring by grouping also called factoring in pairs, we should split the expression into two pairs that have something in common. The idea is that after we factor each pair, we get a binomial common factor.
Step-by-step explanation:
Answer:9 more cups
Step-by-step explanation:
if you subtracts 3 from 12 you get 9 and since you have the same denominator you will keep it the same number
Answer:
It is True.
Step-by-step explanation:
Let's solve the rational equation and if it is ture.
x/8 = 5/4
Cross multiplying, we get
4x = 5*8
4x = 40
Dividing both sides by 4, we get
x = 10.
Therefore, x = 10 is true.
Thank you. :)
