Answer:

The answer is (x + 3) (x - 7) = 0

Step-by-step explanation:

x² - 4x = 21

x² - 4x - 21 = 0

x² - 7x + 3x - 21 = 0

x(x - 7) + 3(x - 7) = 0

(x + 3) (x - 7) = 0

Rewrite without absolute value for the given conditions: y=|x-3|+|x+2|-|x-5|, if x>5

Wittaler [7]

Answer:

y = x + 4

Step-by-step explanation:

Since x > 5, x-3 > 0, x + 2 > 0 and x - 5 > 0

So Ix - 3I = x - 3, Ix + 2I = x + 2 and x - 5 = x - 5

Therefore, y = x - 3 + x + 2 - x + 5

y = x + 4
