1) The hypotenuse of an isosceles right triangle is 8 cm longer than either of its legs. Note that an isosceles right triangle is a right triangle whose legs are the same length. Find the exact length of its legs and its hypotenuse.
2) The length of a rectangle is 9 m longer than its width and the area of the rectangle is 280 m2. Find the exact dimensions of the rectangle.
3) The first leg of a right triangle is 3 cm longer than its second leg. If the hypotenuse has a length of 8 cm, find the exact lengths of the two legs

if the legs are x and the hypotenuse is h, then
h^2 = x^2+x^2
(x+8)^2 = 2x^2
x^2+16x+64 = 2x^2
x^2  16x  64 = 0
Now just use the quadratic formula
If the width is w, then
w(w+9) = 280
If the shorter leg is x, then
x^2 + (x+3)^2 = 8^2

2.D 12. cm
3.A Q
4.C 10
5.A II
6.A (8, 10)
7.B 5
8. A: (x,y) > (x + 1, y + 3)
B: (2, 5) > (2 + 1, 5 + 3) = (1, 2)
100% right... you are welcome that I even gave you the answers lol. anyways 100% right :)no lie
