Marcus paid 45 cents for 2 pencils. At that rate, what would 8 pencils cost? Ill give BRAINLIEST

$1.8

Step-by-step explanation:

divide .45/2 and get .225

multiply this by 8 and get 1.8

it would cost 1.8n

$1.80

Step-by-step explanation:

45/2 = 22.5 cents per pencil

0.225 × 8 = $1.8

(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
