Answer:
68 is the perimeter
the answer would be 48.17
Step-by-step explanation:
to find the perimeter you have to add all the sides
The distance is 3.
Since the x coordinates are the same, we take (-1)-(-4) = 3.
I redrew the triangle (just turned it around it make it easier to understand).
96
36
60
6.51
The coordinates of the point intersection of lines (-1, -1)
If you want solve:
y = -2x - 3, y = 3x + 2
-2x - 3 = 3x + 2 |+3
-2x = 3x + 5 |-3x
-5x = 5 |:(-5)
x = -1
Put the value of x to the first equation:
y = (-2)(-1) - 3 = 2 - 3 = -1
x = -1, y = -1
