Maggie's answer is going to be approximately 2 miles.
The answer is 64+8y+y².
In a perfect square trinomial, you can divide the value of b by 2 and square it, and it will equal the value of c. This works in every other trinomial listed except this one:
8/2 = 4; 4²=16≠64.
84 cupcakes
---------- = divide top and bottom by 1.6= 52.5 cupcakes/1 hour
1.6 hours
so if she can bake 52.5 cupcakes in 1 hours,
multiply by 2 to get 105 cupcakes in 2 hours.
