Determine the factors of 15x2 + 3xy + 10x + 2y.
a. (3x + 2)(5x + y)
b. (5x + y)(2x + 3)
c. (3x + y)(5x + 2)
d. (5x + 3)(2x + y)

The correct option is a.

Step-by-step explanation:

The given expression is

It can be written as

Taking out the common factors from each parenthesis.

Now, again taking out the common factors.

Therefore the correct option is a.

3x^3-x^2+6x-9

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
