Which expression is equivalent to (x2 – 3x)(4x2 + 2x – 9)? a. x2(4x2 + 2x – 9) – 3x b. x2(4x2 + 2x – 9) – 3x(4x2 + 2x – 9) c. x2(4x2 + 2x – 9) + 3x(4x2 + 2x – 9) d. x2(4x2 + 2x) – 3x(2x – 9)

B.

Step-by-step explanation:

The distributivity establish that in order to multiply these two polynomials, first you have to multiply by every element in   and then multiply by every element in as well.

That is exactly what the option B. says, since

in the expresion is being multiplied  by every element in   and also is being multiplied by every element in  .

idk

step-by-step explanation: i just don't

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
