For this case we have the following expression:

Since the denominator is equal, then we can add the numerator.
We have then:

Adding similar terms we have:

Rewriting we have:

Doing common factor in the numerator we have:

Factoring the denominator we have:

Canceling similar terms we have:
Answer:
The simplest form of the expression has 7 in the numerator and m+4 in the denominator.
<u>use the distance formula for this which is:
Sqrt[ (x2-x1)^2 + (y2-y1)^2]
If that is hard to read look it up but pretty much its:
Sqrt [(-12 -12)^2 + (-2-5)^2]
Sqrt [(0)^2 + (-7)^2]
Sqrt [49]
7</u>
Answer:
13.5
8.64
Step-by-step explanation:
1) 9/100 * 150 = 13.5
2) 12/100 *72= 8.64
it means if some thing represents 9 of 100 , so by how much will it represent of a certain number (ex: 150)
