Answer: 105x²y
Step-by-step explanation:
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)
If there were only sandwiches bought, there would be 15, if there were only salads bought there would be 20. There’s probably more than one possibility, but that’s the best I can do, considering how long it’s been since I’ve done this type of problem. I’m all the way to learning determinants, so I really have to think to remember these. Sorry in advance if this doesn’t help at all, I’m not the best at this, but I can still try.
The smallest possible measure of angle h is 90 degrees. Since f and g are complementary angles ( add up to 90 degrees), the h has to at minimum be 90 degrees to equal 180 degrees (supplementary angles).
To isolate x you need to multiply by 1.5 on each side.
![s = 1.5 \times .8](https://tex.z-dn.net/?f=s%20%3D%201.5%20%5Ctimes%20.8)
