Mia tried to solve an equation step by step.
0.1t - 3 = 5

step 1: 0.1t = 2

step 2: t = 20

find mia’s mistake.
a. step 1
b. step 2
c. mia did not make a mistake.

step 1 is incorrect

0.1t = 8

t=80

Step 1

Step-by-step explanation:

Equation: 0.1t - 3 = 5

How to solve:

Therefore, Mia made a mistake in step 1.

(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
