Answer:
-16
Step-by-step explanation:
In this problem, we are adding a negative integer and a positive integer. From this, we already know that the sum will be negative. (- plus + = -)
Since 20 is positive, you can remove the plus sign so your equation looks like
20 - 36
Next, subtract to get -16

Answer:
x = 9±sqrt(7)
Step-by-step explanation:
3(x-9)^2 =21
Divide each side by 3
3/3(x-9)^2 =21/3
(x-9)^2 =7
Take the square root of each side
sqrt((x-9)^2) =±sqrt(7)
x-9 =±sqrt(7)
Add 9 to each side
x = 9±sqrt(7)

I don't know all 12, but I can tell you some.
1. Shade the side of the line that satisfies the inequality.
2. If the inequality sign has an "or equal to" line under it, make the line on the graph connected.
3. If the inequality sign does not have an "or equal to" line under it, make the line on the graph dashed.
4. Isolate y (or the variable that is being used), and keep it on the left side of the inequality.
ok so 7 divided by 12 is 0.5833333 repeating so -0.72 is less because the bigger one is always less in the negatives
