-5x = x + 6(1-x)
-5x = x + 6(1) + 6(-x)
-5x = x + 6 -6x
-5x = x - 6x + 6
-5x = -5x + 6
-5x + 5x = 6
0 = 6 Not equal. No solution.
(2x-5)² = (2x-1)(2x+1) -10(2x-1)
(2x-5)(2x-5) = (2x-1)(2x+1) - 20x + 10
2x(2x-5)-5(2x-5) = 2x(2x+1)-1(2x+1) - 20x + 10
4x² - 10x -10x + 25 = 4x² + 2x - 2x -1 - 20x + 10
4x² - 20x + 25 = 4x² - 20x - 1 + 10
4x² - 20x + 25 = 4x² - 20x - 9
Not equal. No solution.

Answer:
A. 0.4880
Step-by-step explanation:
First, find the z-score:
z = (x − μ) / σ
z = (13.5 − 13.56) / 2.24
z = -0.03
Using a z-score table:
P(z < -0.03) = 0.4880

Answer:
A. x = 0, x = -3, x = 2, and x = -2
Step-by-step explanation:
by moving the terms on the left side to the right side
factor an 
from 
and factor - 4
from 
the equation becomes :
= 0
take 
as a common factor the equation becomes :
= 0
thus
⇒
and
by factoring an x we get :
⇒ = 0 and 
⇒
and 
Thus
the values are :
x = 0, x = -3, x = 2, and x = -2
