12. ABCD is a rectangle with B(-7, 3), C(5, 3), and D(5, -8). Find the coordinates of A. А. (-8, —7) В. (—7, —8) С. (-5, —3) D. (-8, –5)

find the Bezout coefficients and write the gcd (243, 715) a s a linear combination of 243 and 715.

I also need help on this one as well.

Put these camp coordinates on the grid and find their mid points. Camp 1: (3,3) Camp 2: (6,8) Camp 3: (1,10) Camp 4: (-5,-3)
