-12x = 72 Divde both sides by -12 to find the value of x: x = -6
2x2 - 72 would be factored into (2x - 12)(x + 6) or (2x + 12)(x - 6) To double check, multiply each pair: (2x - 12)(x + 6) = 2x2 + 12x - 12x - 72 = 2x2 - 72 (2x + 12)(x - 6) = 2x2 - 12x + 12 x - 72 = 2x2 - 72
As an equation if: 6x = 72 then x = 12
x2 - 18x + 72 = 0 (x - 6)(x - 12) = 0 x ∈ {6, 12}
x=y-8 z=x+12
72.
12 inches equals a foot. 12 x 6 = 72. 72 inches equals 6 feet.
(x + 12)(x - 6) = 0 x = 6 or -12
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
it equals 72. just do 12 X 6
-12x = 72 Divde both sides by -12 to find the value of x: x = -6
Yes it does. They both equal 72.
2
It is 72 inches. (One foot equals 12 inches, thus 6 X 12 equals 72).
72 x 1 8 x 9 4 x 18 6 x 12 36 x 2 3 x 24
1 x 72, 2 x 36, 3 x 24, 4 x 18, 6 x 12, 8 x 9 = 72
1 x 72, 2 x 36, 3 x 24, 4 x 18, 6 x 12, 8 x 9, 9 x 8, 12 x 6, 18 x 4, 24 x 3, 36 x 2, 72 x 1 = 72
