Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results.

Answer:
x = 4
Step-by-step explanation:
The figure is a rhombus when the sides are the same length.
21 -x = 2x +9
12 = 3x . . . . . . . . add x-9 to both sides
4 = x . . . . . . . . . . divide by 3

I know this because 2,000 • 2 = 4,000
Answer:
17b = w
Step-by-step explanation:
17 times the number of bottles = the number of ounces of water
Then you just plug in the numbers you are given
17(51) = w
17 x 51 = 867
<u>51 bottles of water holds 867 ounces</u>
<u />
17b = (51)
divide both sides by 17
51/17 = 3
b = 3
<u>It would take 3 bottles of water to hold 51 ounces</u>
