Step-by-step explanation:
#1) 9=6 - 3 |4p + 9| now we're going to distribute
9= 6 - 12p - 27
9= 6 - 27 - 12p
9= - 21 - 12p
9 + 21= -12p
30= - 12p Now you are going to divide both side by -12
-12:30 = -12:-12p
-5/2= p final answer
#2) - |1 + 4a| = -13 now you going to change the sign
-1 - 4a = -13
-4a = -13 + 1
-4a = -12 now divide both side by -4
-4a:-4 = -12:-4
a = 3 final answer
From 14-21 you have to do it by a calculator and then put it between perfect numbers then minus the bigger perfect number by it and if needed graph on a number line
