Step-by-step explanation:

#1 Simplify the expression 5+8(3+x)

Let's simplify step-by-step.

5+8(3+x)

Distribute:

=5+(8)(3)+(8)(x)

=5+24+8x

Combine Like Terms:

=5+24+8x

=(8x)+(5+24)

=8x+29

#2. Simplify the expression x+3+5x

Let's simplify step-by-step.

x+3+5x

Combine Like Terms:

=x+3+5x

=(x+5x)+(3)

=6x+3

#3. Simplify the expression 5(z+4)+5(2-z)

Let's simplify step-by-step.

5(z+4)+5(2−z)

Distribute:

=(5)(z)+(5)(4)+(5)(2)+(5)(−z)

=5z+20+10+−5z

Combine Like Terms:

=5z+20+10+−5z

=(5z+−5z)+(20+10)

(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
