B and D is correct
PS QT
GOOD LUCK
#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
quick way the one with the 2 closest numbers
other way divide all 4 options
15/36 = 0.41 = 41%
43/92 = 0.46 = 46%
12/30 = 0.4 = 40%
32/52 = 0.62 = 62% Lot 4 had highest percent
2 root (x-5)=2
Divide each side by 2 (in order to isolate the square root):
Root (x-5) =1
Square both sides to remove the radical sign:
(x-5)=1
Solve:
x=6
To be sure that it is not an extraneous solution, check the solution by replacing the value for the variable in the equation.
2 root (6-5) = 2
The square root of 1 is 1.
2(1)=2
This is correct.
10,000 that's how you write ten hundred thousand
