Answer:
answer given in step by step...
Step-by-step explanation:
13x+13(x+1)+13(x+2)=312
13x+13x+13+13x+26=312
39x+39=312
39x=312-39
39x=273
x=7
first number=13x=13*7=91
second number=13(8)=104
third number=13(9)=117
Answer:
The seventh root of a^5
Step-by-step explanation:

is equal to
![\sqrt[7]{a^5}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Ba%5E5%7D)
because
![b^{1/m} = \sqrt[m]{b}](https://tex.z-dn.net/?f=b%5E%7B1%2Fm%7D%20%3D%20%5Csqrt%5Bm%5D%7Bb%7D)
hope this makes sense and helps

Hey there! I'm happy to help!
Sum means you add. Let's call our number n.
n+15
We double the whole thing.
2(n+15)
This is equal to something.
2(n+15)=
Difference means you subtract.
2(n+15)=n-6.
Have a wonderful day! :D
