16x^2 - 9

Step-by-step explanation:

It is possible to solve this without actually multiplying.

There is a rule: (a+b)(a-b) = a^2 - b^2

So, when this is applied here:

(4x-3) (4x + 3) = 16x^2 - 9

All you had to do was 4x^2 and 3^2

Hope this helps.

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.
