PLS HELP!

If the number of Conference participants decreases by 20% compared to last year, there would be 1760 participants this year. If the number of Conference participants increases by 25%, how many more participants would be there this year versus last year?

If 3x+8=3x+8 is it one solution or no solution

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
