Please help, I'm having trouble understanding how to solve this. The midpoint of AB is M(4,-5). If the coordinates of A are (6, -4), what are the coordinates of B?

Simplify the expression and find the missing terms. the simplest form of has in the numerator and in the denominator.

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

Solve: 25 points find the fifth term of an increasing geometric progression if the first term is equal to 7−3 √5 and each term (starting with the second) is equal to the difference of the term following it and the term preceding it.
