Step-by-step explanation:

Here we have , This recipe makes 7 portions of fajitas.  Carly has 900 g of chicken, 1700 g of peppers, 310 g of onion, 50 g of spice mix and 10 tortillas. We need to find How much more of each ingredient will she need to make 21 portions by following this recipe ! Let's find out:

Following are given as :

Recipe: Serves 7         Serves 21                                  

500 g chicken              500(3)=1500 g chicken

800 g peppers             800(3)=2400 g peppers  

100 g onion                  100(3)=300 g onion  

30 g spice mix              30(3)=90 g spice mix

14 tortillas                    14(3)=42 tortillas

Now , Let's calculate more ingredient needed :

Chicken: 1500-900 = 600 g

Peppers: 2400-1700=700 g

Onion : 300-310 = -10 g ( Not needed )

Spice mix : 90-50=40 g

Tortillas : 42-10=32

(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

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
