<span>You can set an equation that relates the total charges to the fixed cost and the number of miles. This is Charge (m) = 4 + 0.60 * m. Where 4 represents the fixed charge and m the numbrer of miles. In this case m = 12, which gives: Charge (12) = 4 + 0.60 * 12 = 11.2. And the answer is that Jenny will charge 11.2 sterling pounds to deliver the cakes.</span>

Well, to find your solution to this problem, I would subtract 84 from 32 = 52. I would divide the number by 2, which equals 26. So, side lengths are 32, 26, and 26.
Or, another one is that 2 sides have the length of 32, so 32+32=64. I would subtract 84 from 64 and get 20. So, side lengths are 32, 32, and 20.
Well it takes 25 min to get dressed then 10 mins to walk there so 25 + 10 = 35 and 35 mins after 7:20 = 7:55 which gives you 20 mins so in total 20 + 35 = 55 so a total of 55 mins to get ready
