Answer:
2x - 3
Step-by-step explanation:
The are of a rectangle is computed using the formula:
A = L x W
The area given is:
2x² + 5x -12
So:
2x² + 5x -12 = L x (x + 4)
![L=\dfrac{2x^{2}+5x-12}{x+4}\\\\](https://tex.z-dn.net/?f=L%3D%5Cdfrac%7B2x%5E%7B2%7D%2B5x-12%7D%7Bx%2B4%7D%5C%5C%5C%5C)
So we can solve this through division:
<u> 2x - 3 </u>
x + 4 | 2x² + 5x - 12
<u> - 2x² + 8x </u>
-3x - 12
<u>- -3x - 12</u>

Yes because if you add up all his expenses $92.87+$11.29+$20.00=124.16 which leaves $104.84 (229-124.16=104.84) left and the X-box game only costs $54.99

Answer:
a(n) = 1/2(-8)^(n-1)
Step-by-step explanation:
The general term of a geometric sequence is ...
a(n) = a(1)×r^(n-1)
where a(1) is the first term, and r is the common ratio.
Here, the first term is a(1) = 1/2. The common ratio is the ratio of any two sequential terms: r = 32/-4 = -8. Then the explicit formula is ...
a(n) = 1/2(-8)^(n-1)
Answer:
Line or scatter graph.
Step-by-step explanation:
I prefer line, although some of the points deviate a bit. But the line shows a definite relationship between mass and length.
See attached graph.
The question is asking you to come up with a real-life example of something that can be represented as 15+ c= 17.50. If I were you I would do sales tax. You bought an item with a 15 dollar price tag, but when you go to check out 2.50 are added in tax to equal 17.50. to solve subtract 15 from 17.50: c= 2.50. Your variable (c) represents the sales tax. Hope that helps! :)
