Answer:
(-8,-1)
Step-by-step explanation:
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.
<em>Answer:</em>
47/48
<em>Explanation:</em>
Since 5 7/8 is so close to 6, it is easier to work this problem by considering the difference.
The serving size is 1/6 of the total amount, so you want to find ...
... (5 7/8) × (1/6)
Following the observation above, we can compute it as ...
... (6 - 1/8) × (1/6) = (6/6) - (1/8)×(1/6)
... = 1 - 1/48
... = <em>47/48</em>
Answer:
x=12
Step-by-step explanation:
-2(x-5)=-14
x-5=-2/-14
x-5=14/2
x-5=7
x=5+7
x=12
