Dear Ffw299, we can find the circumference of a dime using the formula C=2πr. 2x3.14x8.5=59.5 millimeters in circumference.
Answer:
![\frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E2%2B4x-9%7D%7B%282x-3%29%282x%2B3%29%28x-1%29%7D)
Step-by-step explanation:
can be simplified to:
![\frac{2x}{(2x-3)(2x+3)}+\frac{3}{(2x+3)(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B%282x-3%29%282x%2B3%29%7D%2B%5Cfrac%7B3%7D%7B%282x%2B3%29%28x-1%29%7D)
Make them have common denominators so:
![\frac{(2x)(x-1) +3(2x-3)}{(2x-3)(2x+3)(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B%282x%29%28x-1%29%20%2B3%282x-3%29%7D%7B%282x-3%29%282x%2B3%29%28x-1%29%7D)
Simplify:
![\frac{2x^2-2x+6x-9}{(2x-3)(2x+3)(x-1)} = \frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%5E2-2x%2B6x-9%7D%7B%282x-3%29%282x%2B3%29%28x-1%29%7D%20%3D%20%5Cfrac%7B2x%5E2%2B4x-9%7D%7B%282x-3%29%282x%2B3%29%28x-1%29%7D)
I don't think you can simplify that fraction further so that's the answer.
put it into an equation..
15+5v
sum is addition and product is multiplication
Here's what I did and I checked it So it is correct!!
![\frac{7}{28} = \frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B28%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D%20)
![\frac{1}{4} = 0.25](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20%3D%200.25)
25% is your answer.
![28 \times 25\% = 7](https://tex.z-dn.net/?f=28%20%5Ctimes%2025%5C%25%20%3D%207)
