Answer:
48
Step-by-step explanation:
2^2-1 = 3
3^2-1 = 8
4^2-1 = 15
so on so fourth
7^2-1 = 48
Answer:
6 meters
Step-by-step explanation:
This is a right triangle (indicated by the little square in the corner), so it's like half a square. Formula for a right triangle's area is ÷ 2. So in this situation:
÷
Slope intercept is y = mx + b
since they do not give the b(y intercept) you have to use the slope and ordered pair to find the b.
12 = (-2)(8) + b
12 = -16 + b
28 = b
y = -2x + 28
