Answer:

(3x-6)(x-2)

Step-by-step explanation:

To factor this expression, you should divide the 12x into parts.

3x - 6x - 6x +12 works,

so factor 3x^2 and -6x = 3x(x-2)

then factor 6x and 12 to match the first expression, -6(x-2).

Both expressions have (x-2) in common, so you can factor the two resulting expressions: (3x-6)(x-2).

Michael uses a uniform probability model for an experiment using a deck of 45 cards. There are 15 blue card, 15 red cards, and 1

vampirchik [111]

Answer:

P = 2/3

Step-by-step explanation:

45 cards in all

15 blue

15 red

15 green

To figure out the probability of red and blue together, add red and blue.

15 + 15 = 30

Since the total is 45, this is how many 30 will be out of.

30 out of 45 = 30/45

Simplify 30/45 by dividing each side by 15

30 ÷ 15 = 2

45 ÷ 15 = 3

30/45 = 2/3

Problem page isabel runs 7 miles in 50 minutes. at the same rate, how many miles would she run in 75 minutes?

sammy [17]

if isabel runs 7 miles in 50 minutes, then you know she runs 7/50 miles in one minute, right? So multiply that by the number of minutes she did run, and you can find the distance:

 7
------ x 75 =
50

525
------
50

 If you plug that fraction into your calculator, you get 10.5, so 10 and a half miles.
