Answer:
D: (2x + 20°) + x° = 180°
Step-by-step explanation:
Supplementary angles add up to 180°, so that rules out A and C as possible answers.
Answer B has only one angle, so that is out too.
2x + 20° represents one angle, and x represents the other angle
14b
Here, we want to get the greatest common factor of the two terms
The greatest common factor can be obtained by finding the expression that factor the given expression
We have this as;
14b(2a + 3)
So the greatest common factor is 14b
