Step-by-step explanation:
![3.1^4=(3.1)(3.1)(3.1)(3.1)\to\boxed{A}\\\\3.1^4=[(3.1)(3.1)](3.1)(3.1)=(9.61)(3.1)(3.1)\to\boxed{B}\\\\3.1^4=[(3.1)(3.1)][(3.1)(3.1)]=(9.61)(9.61)\to\boxed{D}](https://tex.z-dn.net/?f=3.1%5E4%3D%283.1%29%283.1%29%283.1%29%283.1%29%5Cto%5Cboxed%7BA%7D%5C%5C%5C%5C3.1%5E4%3D%5B%283.1%29%283.1%29%5D%283.1%29%283.1%29%3D%289.61%29%283.1%29%283.1%29%5Cto%5Cboxed%7BB%7D%5C%5C%5C%5C3.1%5E4%3D%5B%283.1%29%283.1%29%5D%5B%283.1%29%283.1%29%5D%3D%289.61%29%289.61%29%5Cto%5Cboxed%7BD%7D)

Sorry if I'm wrong
Answer: 120k - 119
Step-by-step explanation:
Diagonal length is a line from a left corner to a right in a rectangle or square.
Basically making two triangles.
You use the equation a^2+b^2=c^2
So 45.25^2+25.5^2=x^2
2,047.5625+650.25=x^2
2,697.8125=x^2
Then square root them both
51.9404707=x
And when rounding to the nearest number the diagonal length is 52 inches
