Find the sum of the equation
2 answers:
Answer:
Step-by-step explanation:
1) Rewrite in the form , where a = y and b = 1.
2) Use Square of Difference: .
3) Factor .
1 - Ask: Which two numbers add up to 6 and multiply to -7?
-1 and 7
2 - Rewrite the expression using the above.
Outcome/Result:
4) Rewrite the expression with a common denominator.
5) Expand.
6) Collect like terms.
7) Simplify to
Factor y² - 2y + 1 . Factor y² + 6y -7 .
To add or subtract expressions, expand them so their denominators are the same. The least common multiple of (y - 1)² and (y - 1)(y + 2) it is (x + y)(y - 1)². Multiply by Multiply
Since have the same denominator, add their numerators to add them together.
Do the multiplications on y(y + 7) + 6(y - 1) .
Combine like terms in y² + 7y + 6y - 6 .
xpande (y+7)(y−1)² .

Let p = number of people that cast their vote.
p = 0.35(15, 000)
p = 5,250
$7, I think. I would not be too sure about it, though.
(7 1/2) / (3/4) = (15/2) / (3/4) = 15/2 * 4/3 = 30/3 = 10 <== there will be 10 three-fourth ft pieces
