Find the length of the third side. If necessary, round to the nearest tenth.

A² + B² = C²

5² + x² = 9²

25 + x² = 81

x² = 81 – 25

x² = 56

x = √56

x = 7.483

x = 7.48

x = 7.5

I hope I helped you^_^

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
