For this case we have the following expression:

The terms are not similar, so they cannot be added.
<em>Examples of similar terms:</em>

Then, the expression given can only be rewritten as:

This is taking common factor 2 to both terms.

Angle C measures: 
Step-by-step explanation:
When you know the length of the three sides of the triangle and not a single angle, the law of sines is of no use. You need to use the law of cosines. In your case, since you want to find angle "C", you use the following;

Answer:
11 and 18
Step-by-step explanation:
if the smaller number is a
the larger number is a+7
their sum a + (a+7) = 29
2a + 7 = 29
2a = 29-7
2a = 22
a = 22/2
a = 11
the smaller number is 11
the larger number is 11 + 7 = 18
2x-2>8
2x>10
x = 10/2 = 5
x>5
since it is an absolute equation
it could also be x<-3
answer is x>5 or x<-3
