3. multiply the polynomials (a2 + 3a – 4) and (2a2 – a + 5). simplify the answer. show your work.

the answer to this question is in the pic

the probability that a bird is green (.30) is true

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
