Answer:
120
Step-by-step explanation: 90+30
For that case, we factor the numerator and denominator:
Numerator:

We rewrite the term of the medium as a sum of two terms whose product is:

And the sum is:
+7
Those numbers are 6 and 1.

We factor the maximum common denominator of each group:

So:

Denominator:

So, we have:

Simplifying we have left:

Answer:
