Answer:
20 units
Step-by-step explanation:
We are given that
On a coordinate plane , rhombus ABCD in which point A is at (1,1) and point B is at (-2,-3), point C is at (-5,1) and D is at (-2,5).
We have to find the perimeter of rhombus ABCD.
Distance formula :
Using the distance formula
Side AB=
We know that sides of rhombus are equal
Therefore, AB=BC=CD=AD=5 units
Perimeter of rhombus=
Perimeter of rhombus=

Answer:
x = 14
Step-by-step explanation:
If the perimeter is 80, then that is (x+6) + (x+6) + (x+6) + (x+6). If you want to find x, you have to get rid of 6. 6+6+6+6 = 24. The perimeter, 80, minus 56. You then divide 56 by 4 to get x. That is 14. To check, you find (14+6)*4. That is 80.
Answer:
5
Step-by-step explanation:
They are looking for the y intercept. I am assuming that the scale on the x and y axis are counting by 1's. If you start at the origin (0,0) and count up, you will see that the dotting line is going through (0,5)
(24)(.25)=6 dollars more per hour
24+6=30
