12.x^3 when x =-3

pls helppp step by step

11) 14

12) -27

Step-by-step explanation:

11-a when a=-3

Plug in -3 into the equation

11-(-3)

A negative times a negative becomes a positive

So the equation becomes 11+3

Answer is 14

x³ when x=-3

Plug in -3 into the equation

-3³

Solve, which should give you -27

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
