RJ will deposit $1,750 in an account that earns 6.5% simple interest every year. His sister Samantha will deposit $1,675 in an
account that earns 7.5% interest compounded annually.

The deposits will be made on the same day, and no additional money
will be deposited or withdrawn from the accounts.

Which sibling will have more money at the end of four years?

(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

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
