Answer:42x
Step-by-step explanation:just multiply
First one is number 3
Second one is number 2
The constant of proportionality is 4. Also, look at 36, and 9 because you could have just divided it it is not as complicated as you think.
angle of RQS = 45 degrees so
5X-15 = 45
5x=60
x = 12
We can set up an equation: x * (x + 5) = 564, where x is the length of the rectangle we are trying to solve. Using the quadratic formula to solve this, we eventually come up with approximately 21.38 as a value for x. We can verify this by typing 21.38 * (21.38 + 5) into a calculator and seeing that it approximately equals 564.
