I Hope this helps and I hope everything is okay!
Both of these have the same number of solutions (which is 2)
Remember that |5x + 6| means "the absolute value of the expression '5x + 6'", so in this case, 5x + 6 could equal 41 or -41 since the absolute value would "strip away" the positive or negative sign and leave just the number
So, if you solve:
5x + 6 = 41
5x = 41 - 6 = 35
x = 35 / 5 = 7
5x + 6 = -41
5x = -41 - 6
5x = -47
x = -47 / 5
Do the same thing for the other expression:
2x + 13 = 28
2x = 28 - 13 = 15
x = 15 / 2
2x + 13 = -28
2x = -28 - 13
2x = -41
x = -41 / 2
So, both of these expressions have two solutions.
Hope this helps!
Good luck.

Answer:
-16
Step-by-step explanation:
The absolute value function gives the positive value of the argument, so this is ...
-4|-4| = -4·4 = -16
