Answer:

v = -28 and v = 12.

Explanation:

To solve the equation |v + 8| - 8 = -28, you can follow these steps:

First, add 8 to both sides of the equation to isolate the absolute value expression:

|v + 8| - 8 + 8 = -28 + 8

|v + 8| = -20

Now, you have an absolute value equation. There are two possible cases to consider:

Case 1: v + 8 is positive.

Case 2: v + 8 is negative.

Case 1 (v + 8 is positive):

In this case, the absolute value |v + 8| will be equal to its argument, which is (v + 8). So, you have:

v + 8 = -20

Subtract 8 from both sides:

v = -20 - 8

v = -28

Case 2 (v + 8 is negative):

In this case, the absolute value |v + 8| will be equal to the negation of its argument, which is -(v + 8). So, you have:

-(v + 8) = -20

To get rid of the negative sign, multiply both sides by -1:

v + 8 = 20

Now, subtract 8 from both sides:

v = 20 - 8

v = 12

So, there are two solutions to the equation:

v = -28 and v = 12.
