Put the numbers in the equation ,a calculator will be better.
Answer:
A is the correct answer
Step-by-step explanation:
As the question is asking what simple is the correct one and the lines sorry I forgot what the name of them is. Then lines make negatives positive it does not effect a positive number as the number is positive.
27 = 2x + 3
- 3 - 3

2 2
12 = x or x = 12
Answer:
b. {-9, 3}.
Step-by-step explanation:
x^2 + 6x - 27 = 0
We need 2 numbers whose product is -27 and whose sum is + 6.
These are + 9 and - 3. So the factors are:
(x - 3)(x + 9) = 0
(x - 3) = 0 or (x + 9) = 0
x = 3 or -9.
Answer:
x=3.4
Step-by-step explanation:
I could be wrong but I'm pretty sure this is the answer.
