Answer:
20
Step-by-step explanation:
0 to 1 = a difference of 1
1 to 2 = a difference of 2-1 = 1
===============
2 to 4 = a difference of 2
4 to 6 = a difference of 2
6 to 9 = a difference of 3
9 to 12 = a difference of 3
12 to 16 = a difference of 4
16 to 20 = a difference of 4
Well, x=3, -3
If you use a calculator you'll easily be able to figure this out.

What grade is thi?
Answer: 51
Step 1: Replace x in y = 7x + 2 where x = 7.
y = 7(7) + 2.
Step 2: Solve the equation.
y = 49 + 2
y = 51
The correct option is B
∠1 = 96°
∠2 = 84°
∠3 = 84°
∠2 = ∠3
∠1 + 96 + ∠2 + ∠3 = 360°
∠2 = (360 - 96 - 96)/2 = 84°
