Answer:
A
Step-by-step explanation:
-6(4 - x) <= -4(x + 1)
-24 + 6x <= -4x - 4
-24 + 10x <= -4
10x <= 20
x <= 2

Step-by-step explanation:n
<u>13 - 2x </u>
(x +2)² + (x - 3)² - 2x²
<em>Expand.</em>
(x + 2)(x + 2) + (x - 3)(x - 3) - 2x²
x² + 2x + 2x + 4 + x² - 3x - 3x + 9 - 2x²
<em>Bring all the like terms together then simply.</em>
x² + x² - 2x² + 2x + 2x - 3x - 3x + 4 + 9
2x² - 2x² + 4x - 6x + 13
= <u>13 - 2x</u> (or <u>-2x + 13</u> )
third one i think soo ( a push or pull acting on an object )
