Answer:
x = 30
Step-by-step explanation:
1/2(x+6) = 18
Distribute
1/2 x + 3 = 18
Subtract 3 from each side
1/2x +3-3 = 18-3
1/2x = 15
Multiply each side by 2
1/2x*2 = 15*2
Undefined
The square root of a negative number does not exist in the set of real numbers so it would be Undefined
Answer: (-9, -3)
A = (-3, -1)
A' = (-3, -1)*3 = (-9, -3)
