Answer:
b.
Step-by-step explanation:
5*30+3*45>300
150+135
30+45=75
Answer: x = 16, x = 8
Step-by-step explanation:
|a| > 0, there are two solutions
|a| = 0, there is one solution
|a| < 0, there are no solutions
So, in this problem, we have two solutions.
In absolute value, the expression inside can be equal to itself OR its opposite.
Ex: |y| = y, |y| = -y
So, we can write two equations:
x - 12 = 4, x = 16
-x+12 = 4, x = 8
Check: |16 - 12| = |4| = 4
Check: |8 - 12| = |-4| = 4
A=pi*r^2=pi*12^2=452.39 cm^2
Answer:
3p+2p+8-3=15
5p+5-15=0
5p-10=0
5(p-2)=0
(if you want to solve it p=2)
