Answer:
3434
Step-by-step explanation:
3=343+3=3434
44= 32 + 4h
44-32 = 4h
12 = 4h
h = 12/4
h = 3
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.
Okay. Let's start with eliminating answers. Because they're colored in dots, we know that this is a line segment. That means the domain is restricted. So not D.
A, B, C, are in correct because they're just like it's anything larger -1. This is true, but because this is a segment, then we know that it ends at some point.
So it's E.
