Answer:2x3+12x2+10x−24Explanation:The product of these expressions 'means' to multiply them. hence : (x + 3 )(2x2+6x−8) Each term in the 2nd bracket must be multiplied by each term in the 1st.This can be achieved as follows.x(2x2+6x−8)+3(x2+6x−8[2x3+6x2−8x[6x2+18x−24]=2x3+6x2−8x+6xx−24 collect 'like terms'=2x3+12x2+10x−24 is in standard form

I think it would be y plus 3 times 2 equals 5x. I'm not sure if that is what they are asking for.

Which of the following is the equation for a line parallel to y=2x−5 and having a y-intercept of −3? Select one: a. y=−3x−5 b.y=

Firdavs [7]

When we write a line equation in the form

$y=mx+q$

m is the slope of the line, and q is the y-intercept.

Since we want the y-intercept to be -3, our line will look like

$y=mx-3$

In order to fix the slope, remember that two parallel lines have the same slope. So, the slope of the given line y=2x-5 is 2, and since we want a line parallel to this line, our slope will be 2 as well.

Plugging the values, we can finish the equation:

$y=2x-3$
