Answer:
<u>-10x (1 - y)</u>
Step-by-step explanation:
<u>Given :-</u>
Side 1 = (2x + 5xy)
Side 2 = (-7x - 10xy)
<u>To Find :-</u>
Perimeter
<u>Formula :-</u>
Perimeter (rectangle) = 2 (Side 1 + Side 2)
<u>Solving :-</u>
Perimeter = 2 (2x + 5xy - 7x - 10xy)
= 2 (-5x - 5xy)
= <u>-10x (1 - y) => [Solution]</u>
In order to make 119$ he would need to work 7 hours
Since posters cost 9 dollars each and picture frames cost 15, it would be multiplication.
The expression would be 9(6)+15(6) or 9x6+15x6.
You have to multiply these numbers. 9 times 6 would be 54. 15 times 6 would be 90.
Now, we need to add these together. 54 plus 90 would be 144.
The total cost for 6 framed posters would be $144.
