Answer:
22.43 units
Step-by-step explanation:
we know that
The perimeter of a polygon is the sum of its length sides
the formula to calculate the distance between two points is equal to
we have
u(-2,4),v(3,4) and w(3,-4)
step 1
Find the distance uv
substitute the values
step 2
Find the distance vw
substitute the values
step 3
Find the distance uw
substitute the values
step 4
Find the perimeter
![P=uv+vw+uw=5+8+9.43=22.43\ units](https://tex.z-dn.net/?f=P%3Duv%2Bvw%2Buw%3D5%2B8%2B9.43%3D22.43%5C%20units)

Answer:
it takes 1st person 4 hour and second person is 8 hours
Step-by-step explanation:
Let t is the time (t >0)
We have:
- 1st person working rate per one task: 1/t-8
- 2nd person working rate per one task: 1/t
- Working rate per one task from 2 person: 1/3
<=> 1/3 = 1/t + 1/t-8
<=>
<=> ![(t-7)^{2} =25](https://tex.z-dn.net/?f=%28t-7%29%5E%7B2%7D%20%3D25)
<=> t - 7 = 5
<=> t = 12
So it takes 1st person 4 hour and second person is 8 hours
Step-by-step explanation:
A'(0,0),B'(1,2),C(3,2),D(2,0)
it is a parallelogram.
vertical distance is doubled. so false.
angle changes so false.
