Answer:
![2x^{4}+x^{3}-x+2](https://tex.z-dn.net/?f=2x%5E%7B4%7D%2Bx%5E%7B3%7D-x%2B2)
Step-by-step explanation:
To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.
![x^{3}+3x^{2}-2x-6](https://tex.z-dn.net/?f=x%5E%7B3%7D%2B3x%5E%7B2%7D-2x-6)
and
and![-2(x+3)](https://tex.z-dn.net/?f=-2%28x%2B3%29)
So this one is not prime, since you can still factor it.
![x^{3}+2x^{2}-3x-6](https://tex.z-dn.net/?f=x%5E%7B3%7D%2B2x%5E%7B2%7D-3x-6)
and
and![3(x-2)](https://tex.z-dn.net/?f=3%28x-2%29)
So this one is not prime, since you can still factor it.
![4x^{4}+4x^{2}-2x-2](https://tex.z-dn.net/?f=4x%5E%7B4%7D%2B4x%5E%7B2%7D-2x-2)
and![-2x-2](https://tex.z-dn.net/?f=-2x-2)
and![-2(x+1)](https://tex.z-dn.net/?f=-2%28x%2B1%29)
So this one is not prime, since you can still factor it.
![2x^{4}+x^{3}-x+2](https://tex.z-dn.net/?f=2x%5E%7B4%7D%2Bx%5E%7B3%7D-x%2B2)
and![-x+2](https://tex.z-dn.net/?f=-x%2B2)
and -x+2 cannot be further factored.
Therefore,
is a prime.
Answer:
4a+1s
Step-by-step explanation:
50 divided by 12=4 and a is the variable for albums so 4a
12 x 4 = 48
50-48=$2
Which leaves enough money to buy one song therefore 1s
Hope this helps
Have a great day!
First add the number of total larges ordered 22+5=27 then divide 22/27=.814 to make the answer a percent times by 100. .814x100=81.5% to double check you can multiply .814 by number of larges and should get number of hot larges ordered. .814x27=22
The answer is:
940

70
Here's my work:
<span><span><span>949/70</span></span>=<span><span><span><span>70t/</span>70</span></span>
-</span></span>Cross-multiply.<span><span><span><span>
949/70</span></span></span>=<span><span><span><span>70t/</span>70</span></span></span></span><span><span><span>
(949)</span>*<span>(70)</span></span>=<span><span>70t</span>*<span>(70)
</span></span></span><span>66430=<span>4900t</span></span>
-Flip the equation.
<span><span>4900t</span>=66430</span>
-Divide both sides by
4900.<span><span><span><span><span>4900t
</span>4900</span></span></span>=<span><span><span>66430
4900</span></span></span></span><span>t=<span><span>94970</span></span></span>
Hope this helps:)
