Answer: (3x + 11y)^2
Demonstration:
The polynomial is a perfect square trinomial, because:
1) √ [9x^2] = 3x
2) √121y^2] = 11y
3) 66xy = 2 *(3x)(11y)
Then it is factored as a square binomial, being the factored expression:
[ 3x + 11y]^2
Now you can verify working backwar, i.e expanding the parenthesis.
Remember that the expansion of a square binomial is:
- square of the first term => (3x)^2 = 9x^2
- double product of first term times second term =>2 (3x)(11y) = 66xy
- square of the second term => (11y)^2 = 121y^2
=> [3x + 11y]^2 = 9x^2 + 66xy + 121y^2, which is the original polynomial.
1 cup = 8 fluid ounces.
6.875 cups = ? fluid ounces.
8*6.875=55.
Your answer would be 55 fluid ounces.

Hello!</h2>
The answer is:
<h2>
Why?</h2>
To solve the problem we need to add/subtract like terms. We need to remember that like terms are the terms that share the same variable and the same exponent.
For example, we have:
We have that we were able to add just the terms that were sharing the same variable and exponenr (x for this case).
So, we are given the expression:
Hence, the answer is:
Have a nice day!

:) ask if you'd like to know how I figured that out
A.32 it’s not very complicated you just have to find the value of A and B then multiply them together
