Step-by-step explanation:
Are you solving for x or y?
A) 55 people said their favorite vehicle color is red
B) 80 people said their favorite vehicle color was blue while 60 people said their favorite vehicle color was white
C) 45 said their favorite vehicle color was black while 10 people said their favorite vehicle color was silver
Explanation:
Consider the case a = -1. Then the expression becomes ...
(-1+1)(-1+1) > (-1-1)(-1-1) . . . . test case
0·0 > (-2)(-2) . . . . . simplified a bit
0 > 4 . . . . . . . . NOT TRUE
_____
If we subtract the right side from both sides, the inequality becomes ...
(a+1)(a+1) -(a-1)(a-1) > 0
a² +2a +1 -(a² -2a +1) > 0
4a > 0
a > 0
The inequality is only true for positive values of "a". For a ≤ 0, the inequality will not be true.
