How many weeks will it take to Sheila to achieve her desired weight goal

Step-by-step explanation:

I would aay about 16 weeks, but thats just an estimate

(192-124)/4 = weeks of dieting necessary

Step-by-step explanation:

Don't let the graph spook you. sometimes they put unnecessary information into problems so you have to sort through a find what is important.

take the change in weight (initial - final) and divide it by the amount sheila thinks she can lose in a week. this will give you the necessary weeks.

how would you find how many days it would take her?

how much weight does sheila lose per day?

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

the answer is simply just 6n add the two together as they have an n
