Factor completely −3x3 + 12x2.

A. −x(3x2 − 12x)
B. −3x2(x − 4)
C. 3x(−x2 + 4x)
D. 3x2(−x + 4)

B. −3x² (x − 4)

Step-by-step explanation:

-3x³ + 12x²

-3x² ( x - 4 )  ⇒ B

y/x=18

step-by-step explanation:

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
