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.
I got -19/655 and i know for sure this isnt the correct answer.
Answer:
10 degrees
Step-by-step explanation:
(5x(10))+3=53 degrees
(3x(10))+7=37 degrees
53+37=90 degrees
Answer:
10^2 × 10^2
Step-by-step explanation:
Given that
Write 100 times 100 that would be multiplying to the power by 10
So based on the above information
The equation that would be developed is
10^2 × 10^2
The same would be represented as an answer
