Lucas and Erick are factoring the polynomial 12x^3 - 6x^2 + 8x - 4. Lucas groups the polynomial (12x^3 + 8x) + (-6x^2 - 4) to factor. Erick groups the polynomial (12x^3 - 6x^2) + (8x - 4) to factor. Who correctly grouped the terms to factor? Explain.
please I really need help!!!

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

is means division by fractions

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
