If x = y + 2, then (x - y)³ = ?

A.) 12

B.) 8

C.) 1

D.) -1

E.) -4

D.) -1

E.) -4

x = y + 2

(x - y)³

= (y + 2 - y)³ {substituted (y + 2) for x}

= (2)³ {combined like terms}

= 8 {evaluated exponent}

(x - y)³

= (y + 2 - y)³ {substituted (y + 2) for x}

= (2)³ {combined like terms}

= 8 {evaluated exponent}
