Use the distance formula to find the distance between the two points

9.) c(-9,-1) and d(7,3)

10.) e(5,-5) and f(1,-6)

11.) g(-5,3) and h(2,-8)

9.) -2/2 = -1

10.) -6/-11 or 6/11

11.) -3/-11 or 3/11

Step-by-step explanation:

this is easy XD

So, first step the midpoint formula: (x1 + x2 / 2, y1 + y2 /2 )

9.) c(-9,-1) and D(7,3)  > you should know the x and y and plug in :D

10.) E(5,-5) and F(1,-6) > you should know the x and y and plug in :D

11.) G(-5,3) and H(2,-8)> you should know the x and y and plug in :D

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
