Question

Simplify and determine the coefficient of (-x)(3y)(-2x). a.-4 b.1/3 c.1 d.4

Answer 1

The coefficients in the equation (-x)(3y)(-2x) are the constants -1, 3, and -2. 
In order to simplify and determine only one coefficient we should multiply all  three constants together to get only one numerical constant .
The commutative law says hat you can rearrange a multiplication any way you want. so, (-1)*3*(-2)=(-3)*(-2)=6
The equation can be also simplified written as:
6x^2y
None of the option is the solution.

Answer 2

well.. i just got the same problem.. With the same multiple choice.. I'm going to put one. I might update with my score on the test after i finish. (this is an old question that i thought i might answer with my guess)
