a and b are teh legnth s of the legs
c is the legnt o fthe hyptonuse

8^2+13^2=c^2
64+169=c^2
233=c^2
square root both sdies
aprox 15.264=c

the legnth is aprox 15.26 cm

Answers

Just divide and multiply BUT when you divide or multiply by negative numbers you switch the symbol.

#1 is -18÷-3= 6; x is less than 6
#2 is 4×-2= -8; y is less than -8
#3 I don't understand the question
#4 -1.5×-2= 3; c is less than 3
#5 is 1/20×-5= -0.25; x is less than -0.25
#6 is not possible
#7 is 3÷-2=-1.5; b is greater than -1.5
#8 is -70÷-0.5= 35; a is greater than 35
