Answer:
30 units
Step-by-step explanation:
If the w=5 and we know that the length is 2(5)=10
For perimeter, there are two sides.
2(10)+2(5)=30 units
Both the points have a coordinate where y is -1, so the equation is simply -1
y=-1
however if you wanted to really show the working out, it looks like this:
y=mx+c
m=change in y/change in x
m=(-1-1)/(-5+0)=0
subsitute one of the coordinates into y=mx+c
-1=0+c
c=-1
so then y=-1

Explanation :
255/20 = 12.75
12.75 - 2.90 = 9.85
9.85 x 10 = 98.50
X= -1

Answer:
28
Step-by-step explanation:
![5x -7\\x =7](https://tex.z-dn.net/?f=5x%20-7%5C%5Cx%20%3D7)
Substitute 7 for x in the given equation
![5x -7\\\\= 5(7) -7\\\\= 35-7\\\\= 28](https://tex.z-dn.net/?f=5x%20-7%5C%5C%5C%5C%3D%205%287%29%20-7%5C%5C%5C%5C%3D%2035-7%5C%5C%5C%5C%3D%2028)
