-x^2 + 7 is the simplified expression
Answer:
1.5
Step-by-step explanation:

Ok so if The area of the square is 15 * 15. then what you need to do is subtract the total area of the 4 white sectors of a circle.
Together, the 4 sectors form one circle of radius 7.5. Now yu need to have in mind that the area of the circle they jointly form is pi * (7.5)^2. So 15 * 15 - pi * (7.5)^2 =<span>48.29

(3, 62)
Since that second equation is equal to y, you can substitute the entire thing into the top equation, getting rid of the y and solving for x. It equals 3.
You can then plug 3 in for x on either equation, which should be 62.
Its two squares, so you need to start by finding the perfect roots that go into 117. If you need more help after that just comment :)
