You can only add exponents if you are multiplying two of the same variable together. For example,
![x^{12} \times x^4 = x^{16}](https://tex.z-dn.net/?f=x%5E%7B12%7D%20%5Ctimes%20x%5E4%20%3D%20x%5E%7B16%7D)
You take them away if you are dividing.
<span>
![x^{12} \div x^4 = x^{8}](https://tex.z-dn.net/?f=x%5E%7B12%7D%20%5Cdiv%20x%5E4%20%3D%20x%5E%7B8%7D)
In a polynomial equation, you can add together two of the same variable if they have the same exponent
</span>
![3x^4 + 7x^4 = 10x^4](https://tex.z-dn.net/?f=3x%5E4%20%2B%207x%5E4%20%3D%2010x%5E4)
Or you can take them away in a similar fashion,
<span>
![3x^4 - 7x^4 = -4x^4](https://tex.z-dn.net/?f=3x%5E4%20-%207x%5E4%20%3D%20-4x%5E4)
But you cannot add two (or more) different exponents,
</span>
![6+4x+7x^2 = 6+4x+7x^2](https://tex.z-dn.net/?f=6%2B4x%2B7x%5E2%20%3D%206%2B4x%2B7x%5E2)
(it does not get any simpler)
I hope this has answered your question, if not, leave a comment and I'll update the answer.
he divided by 2 instead of taking the square root so the actual answer should be 26 and for the second the 20 is across from the 90 so its suppose to be c
the answer should be 16
Answer:
282.5 inches squared
Step-by-step explanation:
A triangle is half the area of a square.
So we will solve the area as if we were finding the area for a square, and then we halve the result.
Length multiply by height to get the area:
28.25 × 20 = 565 inches squared
Now, half the answer to get the area of the triangle:
565/2=282.5 inches squared
Answer:
1 full moon per 6 days
I'm going to guess that is what you want.
