Answer: You should cut out squares that are 4 inches by 4 inches.
One of the ways to do this problem is write and graph an equation. We can write an equation for the volume of this shape and then use a graphing calculator to graph it. If we look where the graph crosses 440, we will have our solution.
The volume needs to be 440. If we let x equal the side of the square that is cut out, we have the following dimensions.
Length = 19 - 2x
Width = 18 - 2x
Height = x
Volume = LWH
So our equation could be: y = (19 - 2x)(18 - 2x)x
If you graph that equation, it will intersect at the point (4, 440). Therefore, our square could be 4 by 4 inches.
Answer:
They subtracted the values incorrectly
Step-by-step explanation:
The formula for finding the distance between two points is this:
![\sqrt{} (x_{2} -x_{1})^{2} + (y_{2} -y_{1} )^{2}](https://tex.z-dn.net/?f=%5Csqrt%7B%7D%20%28x_%7B2%7D%20-x_%7B1%7D%29%5E%7B2%7D%20%20%20%2B%20%28y_%7B2%7D%20-y_%7B1%7D%20%29%5E%7B2%7D)
The person subtracted the variables incorrectly and subtracted x1 from x2 and y1 from y2 instead of the other way around.
To correctly solve it, do this:![\sqrt{((-7-(-1))^2+(-6-2)^2} = \sqrt{(-6)^{2} + (-8)^{2} } = \sqrt{36+64} = \sqrt{100} = 10](https://tex.z-dn.net/?f=%5Csqrt%7B%28%28-7-%28-1%29%29%5E2%2B%28-6-2%29%5E2%7D%20%3D%20%5Csqrt%7B%28-6%29%5E%7B2%7D%20%2B%20%28-8%29%5E%7B2%7D%20%20%7D%20%3D%20%5Csqrt%7B36%2B64%7D%20%3D%20%5Csqrt%7B100%7D%20%3D%2010)
