Ok so just do
a^2+b^2=c^2
c=longest side
a and b are the other sides
input for a and b and c and see which ones are true
A. 1^2+3^2=10^2
1+9=100
10=100
false
B, 4^2+5^2=9^2
16+25=81
41=81
false
C. 9^2+40^2=41^2
81+1600=1681
1681=1681
true
D. 16^2+30^2=44^2
256+900=1936
1156=1936
false
answer is C
Taylor has x cats
Staci has x+7 cats
I believe the answer is C
