1. let x be the number of months paid. 2. let 33x be the dollar value of the cost paid after x months (no initial fee yet) 3. let 33*5=165 be the cost paid on monthly basis for 5 months . But the total cost is $225 dollers after 5 months. the implies that the membership fee is 225 -165=dollers. 4. let TC be the total cost. 5. then the total cost TC=33x+60. 6. after 10 months , total cost TC= 33*10+60=330+60=390dollers.

Given:
_____________________________________________________
" (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 " .
