Answer:
Question 13: 90, Question 14: y =
, Question 15: x =
, Question 16: y =
.
Step-by-step explanation:
Answer:
Option C. (2x+3)(6x – 5) is the correct answer.
Step-by-step explanation:
Given polynomial(trinomial) is:

The given trinomial is quadratic. Factorization will be as follows:
Multiplying the co-efficient of x^2 and the constant results in 180. We have to make factors of 180 in such a way that their sum of difference is equal to the co-efficient of x.
The required factors are 18 and 10
So,

Hence,
Option C. (2x+3)(6x – 5) is the correct answer.
Its D since 6 would go to both numbers in the parentheses.
