To calculate it use pythagoras: a^2+b^2=c^2
7^2+10^2=49+100=149
calculate the square root:
![\sqrt{149}=12.2](https://tex.z-dn.net/?f=%5Csqrt%7B149%7D%3D12.2)
so the diagonal is about 12.2 inches long
Wait i don’t understand how they are fractions. lmk
A because I know I’m right and I calculated it.
It would be 70r if you are using distributive property
![98 \div 51450](https://tex.z-dn.net/?f=98%20%5Cdiv%2051450)
solve it under 10 minutes
