Perimeter of triangle = sum of all its sides = 2.8 + 2.7 + 0.7
Perimeter = 6.2 meters
So its in the pic i hope it helps it is correct because i am in highschool i like to help people
Answer: (12, 0) and (0, 8)
Step-by-step explanation:
This equation is in standard form. We can sub in a number for x to solve for y and vice versa.
Let's sub in 0 for x.

When x is 0 y is 8 giving us the coordinate (0, 8).
Now lets sub in 0 for y

When y is 0 x is 12 giving us the coordinate (12, 0)
