(x - 4)(x^2 + 3x + 2) = 
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 = 
x^3 -x^2 - 10x - 8

Help me please 7−s/2>3
Alja [10]

Answer:

s < 8

Step-by-step explanation:

7−s/2>3

Subtract 7 from each side

7-7−s/2>3-7

-s/2 > -4

Multiply each side by -2.  Remember to flip the inequality since we are multiplying by a negative.

-s/2 * -2 < -4*-2

s < 8
