Find the area of the region enclosed by the curves y^2-2x=7 and x-y=4. And please simplify. Thank you.

Mary had at least an 80% on her test write an inequality to represent this situation

Which of the following represents a number squared is equal to twenty more than nine times that number ? a) x squared = 9x + 20 b) x squared = 20x + 9 c) x squared > 9 + 20x d) x squared = 9 + x + 20

Solve 2^x=32 and rewrite this equation in a logarithmic form
