Marco needs to buy some dog food. At the nearest store, 2 bags of dog food cost $6.50. How much would Marco spend on 3 bags of dog food?

which expression represents the approximate length of bc?

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

-5, your answer was correct

.16 as a fraction equals 4/25 and you cant simplify that so i'm pretty sure this is the answer
