I have a few out of a hundred if anyone is willing to help me out and also explain the steps? Thank you in advance!
1) In what quadrant does the point (-2,5) lie?
2)Simplify: 3 times square root of 63
square root of 10 times (square root of 2 plus 2)
3)Find the hypotenuse when two legs of a right triangle are 6cm and 3 cm.
4) Solve for y: y-4 =3
x+3 4
5) factor: x squared-5x+6
6) let y= x squared +2x-3
7) Solve for x by taking the square root of both sides: (x-2) squared = 9
I know it's a lot and thank you again!

1. quad 2
2. 3√63 = 3√(9•7) = 3•3√7 = 9√7
the rest of that blurs into ambiguity
3. h² = 6² + 3² = 36+9 = 45, h = √45 = 3√5
4. y - 4 = 3x + 34, y = 3x + 38
5. x² - 5x + 6 = (x-2)(x-3)
6. y = x² + 2x - 3. where's the question?
7. (x-2)² = 9, x-2 = ±3, x = 2+3 = 5 or x = 2-3 = -1

3. a^2 + b^2 = c^2
1. 6^2 + 3^2 = c^2
2. 36 + 9 = 45
3. Take the square root of 45 to find c.
