Answer:
3, -1
Step-by-step explanation:
First we should figure out how many times 2 goes into 69,(because each tile is 2 feet long) and I am going to do that by dividing 69 by 2. I got 34.5, so we can just say 35 to make it easier. So we now know we need 35 tiles, but they come in boxes of 6, so we will need to divide 35 by 6. It didn't make a full number (it was 5.833) but we need a full number of tiles so we will round up.
Our final number of how many boxes of tiles is 6.
A property of rectangles is that opposite sides are congruent. In this case, since QT and RS are opposite sides, they are equal to each other. With this knowledge, you can form the equation 
to solve for x.
Firstly, subtract both sides by 8: 
Next, divide both sides by 4 and your answer will be 
, or the third option.
The answer is 60 bc -3 x -4 is 12, and 12x5 is 60
