There are some errors in your table. Column 1, for example, should be all odd numbers. Columns should alternate even/odd.
It can be useful to build a spreadsheet that fills these numbers.
To calculate it use pythagoras: a^2+b^2=c^2
7^2+10^2=49+100=149
calculate the square root:

so the diagonal is about 12.2 inches long
Answer:
no bc they r swapped and 40 is higher
Step-by-step explanation:
k
bearing in mind that the centroid in a triangle cuts each of the three medians in a 2:1 ratio.
since we know that A C = 12, let's split it in a 2:1 ratio then, cleary from the picture the larger is F C, so F C : A F is on a 2:1 ratio.

-they can get the same answer
