Answer:
Well you can't go thur a month because $700 by 12 months is $8400.
Step-by-step explanation:
700 x 12 = 8400
8400 - 2800 = -5600
So you would be negitative.
Answer:
252 is the least common multiple
Step-by-step explanation:
The sum of functions is given as:

In this case we have:
![(f+g)(x)=5x+\sqrt[]{x-1}](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D5x%2B%5Csqrt%5B%5D%7Bx-1%7D)
The domain of the functions is any number that makes the squared root a real number, then:

Hence the domain of the functions is:
X = 7 / sin(45)
x = 7 / sqrt(2)/2
x = 7 sqrt(2)
