| 7 + m | - 4 > 8 A. m > -2 or m < -20

B. m > 7 or m < 0

C. m > 5 or m < -19

D. m > 9 or m < -15

m > 5 or m < -19

Step-by-step explanation:

We are given the Inequality:

First, add both sides by 4.

Absolute Value Property

Given a = any expressions and b = any positive numbers, zero or any expressions.

From the Inequality, change > to equal

Subtract 7 both sides.

±12-7 can be 12-7 = 5 or -12-7 = -19

Refer to the attachment. The region is when the absolute value function is greater than constant function y = 12 or a blue horizontal line.

Since the absolute graph is above constant graph when x > 5 and x <-19.

Therefore,

the answer is 13 cm
