Answer:
Perimeter = 22.434
Step-by-step explanation:
To find the perimeter we need to find the length of all three sides, and we do that by finding the distance between the points that form the sides:
The formula for the distance between two points is:

side UV:

side VW:

side UW:

So the perimeter is:

uhm do ur own homework
it's okay to ask for help but it's kinda petty to ask someone to do everything
do u even have alot of homework?
Answer:
(5, -2)
Step-by-step explanation:
x + y = 3 can become x = 3-y
we are going to use substitution
now plug x = 3-y into the other equation
2(3-y) + 3y = 4
6-2y+3y = 4
6 + y = 4
subtract 6 from both sides
y = -2
now plug in y back into one of the equations, it doesn't matter which one. I am going to use the x + y = 3 equation
x -2 = 3
x = 5
