X - 3 divided by 12 - 4x?
(x - 3)/(12 - 4x) = (x - 3)/[4(3 - x)] = (x - 3)/[-4(x - 3)] = 1/-4 = -(1/4)
Write three ways to find 3 x 2 x 4?
3 x 2 x 4 = 24 (3 x 2) x 4 = 6 x 4 = 24 3 x (2 x 4) = 3 x 8 = 24 2 x (3 x 4) = 2 x 12 = 24
Is multiplication distributive over multiplication?
No, multiplication is associative. 5 x (4 x 3) = 4 x (5 x 3) = 3 x (5 x 4) = 5 x 4 x 3 = 60

X - 3 divided by 12 - 4x?
(x - 3)/(12 - 4x) = (x - 3)/[4(3 - x)] = (x - 3)/[-4(x - 3)] = 1/-4 = -(1/4)
Find x when X to the power of -5 thirds equals 4 without using a calculator?
x^(-5/3) = 4 1/x^(5/3) = 4 x^(5/3) = 1/4 [x^(5/3)]^(3/5) = (1/4)^(3/5) x = 1/4^(3/5) or, x = 4^(-3/5) Check: x^(-5/3) = 4 [4^(-3/5)]^(-5/3) = 4 ? 4 ^(15/15) = 4 ? 4^1 = 4 ? 4 = 4

Divide x2 - x - 12 by x - 4?
(x^2 - x - 12) = (x^2 - 4x + 3x -12) = x(x -4) + 3(x -4) = (x-3) x (x-4) Hence (x^2 - x - 12) divided by (x -4) is (x-3)
How can you get 24 by using only the numbers 8 3 3 4?
One solution is 8 x (4 - 3/3) = 8 x (4 - 1) = 8 x 3 = 24 And another, 8 x 3 x (4 - 3) = 8 x 3 x 1 = 24 And a third, (3 + 3) x ( 8 - 4) = 6 x 4 = 24
Is multiplication distributive over multiplication?
