12.4 because 62 divided by 5 = 12.4
Answer:
Given all right triangles
<u>Use Pythagorean to find the missing side:</u>
- a² + b² = c², where c- hypotenuse
=1=
- x² = 6² + 3² = 45
- x = √45
- x = 6.7
=2=
- x² = 12² + 5² = 169
- x = √169
- x = 13
=3=
- x² = 2² + 5² = 29
- x = √29
- x = 5.4
Answer:
The unit rate of change is of 
Step-by-step explanation:
We are given a set of points (x,y).
To find the unit rate of change, we take two points, and divide the change in y by the change in x.
Points (4,9) and (8,12)
Change in y: 12 - 9 = 3
Change in x: 8 - 4 = 4
Unit rate of change: 
divide 63 by9
63 / 9 = 7
each piece is 7 meters long
