what is the value of x in the equation?√10x-21 = x : x = 7 and x = 3

when solved correctly, the equation √-2x-5 = x + 4 has solutions of x = −7 and x = −3which, if any, of the solutions are extraneous? : only x = -7 is extraneous

the pythagorean theorem can be used to find the missing side length of a triangle when two other side lengths are known.a: 20b: ?c: 29what is the value of b? : 21
