Answer:
24.3 units (3 s.f.)
Step-by-step explanation:
Since a square has 4 equal sides,
perimeter of ABCD= 4(length of AB)
Distance between 2 points
=![\sqrt{(y1 - y2)^{2} + (x1 - x2)^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%28y1%20-%20y2%29%5E%7B2%7D%20%2B%20%28x1%20-%20x2%29%5E%7B2%7D%20%20%7D%20)
Length of AB
![= \sqrt{( { - 2 - 4)}^{2} + {(2 - 3)}^{2} } \\ = \sqrt{( - 6)^{2} + ( - 1)^{2} } \\ = \sqrt{37}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%28%20%7B%20-%202%20-%204%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%282%20-%203%29%7D%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%28%20-%206%29%5E%7B2%7D%20%20%2B%20%28%20%20-%201%29%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B37%7D%20)

Alright, to average 1000 per day over 3 days, we have 1000*3=3000 dollars. Since we already have 2 days, we do 3000-1240-921=839
Answer:
x=47is your answer
3x-11=130(alternate angle)
3x=130+11
x=141/3=47
