Answer:
1 + root 5, 1 - root 5
Step-by-step explanation:
I assume you mean 3x^2-6x-12=0.
First, note that you can divide both sides by 3. You get:
x^2-2x-4=0
Use the quadratic equation.
Therefore, x=1 + root 5, 1 - root 5
Answer:
area: 72 perimeter: 36
Step-by-step explanation:
area of big rectangle, 10x6=60

The answer would be (-2,10)
Explanation:
Since it is telling us to focus on point A, we should do so.
It tells us to shift -6 units horizontally. This means we should shift point A to the left 6 units.
Then it wants us to reflect over the x-axis. The x-axis is the horizontal line. Flipping it across just means changing the x value to the opposite.
Therefore it is (-2,10)
