Answer:
x=4 x=-2
Step-by-step explanation:
x+4 x
----------- = ------------
4 x-2
Using cross products
(x+4)(x-2) = 4x
FOIL
x^2 -2x +4x -8 = 4x
Combine like terms
x^2 +2x -8 = 4x
Subtract 4x from each side
x^2 +2x-4x -8 = 4x-4x
x^2 -2x-8 =0
Factor
What 2 numbers multiply to -8 and add to -2
-4*2 =-8
-4+2 = -2
(x-4) (x+2) =0
Using the zero product property
x-4+4 =0+4 x+2-2=0-2
x=4 x=-2
Given X = {15, 22, 33, 44, 89, 165, 1025} and Y = {-5, 15, 33, 88, 99, 150, 160, 1025}, which of the following statements is fal

in the second one its the union of x and y which means that you must list all numbers in x and y without repetition
the third one states that 15,33,1025 are the only numbers that are common between x and y.
so as a breif the first one is wrong
