Answer: ![676units^{2}](https://tex.z-dn.net/?f=676units%5E%7B2%7D)
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a square, which is:
![A=s^{2}](https://tex.z-dn.net/?f=A%3Ds%5E%7B2%7D)
Where s is the lenght of a side of the square.
2. By definition, the sides of the square have equal lenghts. You can calculate the lenght of a side by calculating the distance between two vertices of the aquare:
![s_{AB}=\sqrt{(2-(-8))^{2}+(-5-19)^{2}}=26units](https://tex.z-dn.net/?f=s_%7BAB%7D%3D%5Csqrt%7B%282-%28-8%29%29%5E%7B2%7D%2B%28-5-19%29%5E%7B2%7D%7D%3D26units)
Where
is the lenght of the side AB.
3. The area is:
![A=(26units)^{2}=676units^{2}](https://tex.z-dn.net/?f=A%3D%2826units%29%5E%7B2%7D%3D676units%5E%7B2%7D)
Answer:
$16.60
Step-by-step explanation:
2.5x + 1.25(x - .20) = 31.25
2.5x + 1.25x - .25 = 31.25
3.75x - .25 = 31.25
3.75x = 31.25 + .25
3.75x/3.75 = 31.50/3.75
x = 8.40
y = x - .20
y = 8.20
1x + 1y = 16.60
Answer:
I'm pretty sure for the percent question the answer would be A because 6% of 40,000 is 2400 and if I multiply that 5 times I get 12000 so I believe its A!
