Answer:
8 units
Step-by-step explanation:
find the distance of the lines through coordinates given
distance formula: ![\sqrt{(x_{1}-x_{2})+(y_{1} -y_{2} ) }](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_%7B1%7D-x_%7B2%7D%29%2B%28y_%7B1%7D%20-y_%7B2%7D%20%29%20%20%7D)
i) CD=![\sqrt{(4-4)^2 +(-1+5)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%284-4%29%5E2%20%2B%28-1%2B5%29%5E2%7D)
CD=![\sqrt{0+4^2}](https://tex.z-dn.net/?f=%5Csqrt%7B0%2B4%5E2%7D)
CD=4 units
ii) DE=![\sqrt{(4-2)^{2}+(-5+3)^2 }](https://tex.z-dn.net/?f=%5Csqrt%7B%284-2%29%5E%7B2%7D%2B%28-5%2B3%29%5E2%20%7D)
DE=![\sqrt{(2)^2+(-2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%282%29%5E2%2B%28-2%29%5E2%7D)
DE=![\sqrt{8}](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D)
DE= 2 units
iii) ED=![\sqrt{(2-4)^2+(-3+1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%282-4%29%5E2%2B%28-3%2B1%29%5E2%7D)
ED=![\sqrt{(-2)^2+(-2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-2%29%5E2%2B%28-2%29%5E2%7D)
ED=![\sqrt{8}](https://tex.z-dn.net/?f=%5Csqrt%7B8%7D)
ED= 2 units
perimeter of polygon= 2 units+ 2 units+ 4 units
=8 units
Answer:
y=x-3
Step-by-step explanation:
Answer:
the number is 3
Step-by-step explanation:
Perhaps you'd like to find the number.
If n represents the number, we can write the relationship as ...
3n -1 = n +5
Adding 1-n to both sides gives ...
2n = 6
n = 3 . . . . divide by 2
The number is 3.

<em>Check</em>
The product of the number and 3 is 9. One less is 8. That is 5 more than the number itself: 8 = 3 + 5.
