" (2x <span>− 2y) (2y + 8) " ; Simplify .
_____________________________________________________
We starting by "expanding" the expression.
_____________________________________________________
<u>Note</u>: " (a + b)(c + d) = ac + ad + bc + bd " ;
_____________________________________________________
</span>→ (2x * 2y) + (2x * 8) + (-2y * 2y) + (-2y * 8) ;
= 4xy + 16x + (- 4y² ) + (-16y) ;
= 4xy + 16x − 4y² <span>− 16y ;
</span>→ which is: "Answer choice: [D]: " 4xy + 16x − 4y² − 16y " .

9 quarters = $2.25; and 16 nickels= $0.80.
9 quarters plus 16 nickels is 25 coins and $2.25 + $0.80 = $3.05
