Calculate the determinate of this matrix [4 2 3/ 1 1 4/ 0 1 1] step 1: what is the first step?

(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

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
