When doing this equation, draw a big X on your paper. At the top of the x you do A times C. At the bottom, you put the B. To factor, you need to find what two numbers MULTIPLY together to equal the A times C, and that add together to get the B.

In all you will get (q+7) (q-6)

Answer:

a) 12x + 22 b) 17 $x^{2}$ - x

Step-by-step explanation:

Perimeter is the sum of the each side length.

The first example is a rectangle so the (4x+8) and the (2x+3) are doubled.

(4x+8) x 2 = 8x+16

(2x+3) x 2 = 4x + 6

12x+22

(6 $x^{2}$ - 12x) + (2 $x^{2}$ + x) + (9 $x^{2}$ + 10x)

combine like-terms.

17 $x^{2}$ - x

Step-by-step explanation:

Each number cube has 6 possible values, so there are 6⁴ = 1296 possible permutations. Only 1 of those permutations is all ones. Therefore, the probability is 1/1296.
