34 number line. pi, 3 1/15 Square 15, Square 9, 7/2

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

35/2 is it i think maybe

the closest answer i got was 75 divided by 9 = 8.3
