Answer:
X = 2
Step-by-step explanation:
44 + 104 + (18+7x) = 180
Simplify
5*6=20+y
30=20+y
30-20=20-20+y
10=y
Check answer by using substitution method
5*6=20+y
30=20+10
30=30
Answer is y=10
Answer:
14.88x + 8.88y =
Step-by-step explanation:
This may be wrong but I think it’s this
Combining the like-terms, the result of the addition of polynomials f(x) and g(x) is given by:
![f(x) + g(x) = 21x^3 + \frac{5}{4}x^{\frac{1}{2}} + 19x^{-\frac{1}{4}} + 8x^{-4}](https://tex.z-dn.net/?f=f%28x%29%20%2B%20g%28x%29%20%3D%2021x%5E3%20%2B%20%5Cfrac%7B5%7D%7B4%7Dx%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%2B%2019x%5E%7B-%5Cfrac%7B1%7D%7B4%7D%7D%20%2B%208x%5E%7B-4%7D)
<h3>How do we add polynomials?</h3>
We add polynomials combining the like-terms, that is, adding terms with the same exponent.
In this problem, the polynomials are:
Combining the like terms, the addition is given by:
![f(x) + g(x) = \left(3 - \frac{7}{4}\right)x^{\frac{1}{2}} + (7 + 12)x^{-\frac{1}{4}} + 8x^{-4} + 21x^3](https://tex.z-dn.net/?f=f%28x%29%20%2B%20g%28x%29%20%3D%20%5Cleft%283%20-%20%5Cfrac%7B7%7D%7B4%7D%5Cright%29x%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%2B%20%287%20%2B%2012%29x%5E%7B-%5Cfrac%7B1%7D%7B4%7D%7D%20%2B%208x%5E%7B-4%7D%20%2B%2021x%5E3)
