3. Solve. 3x^2-5x-1=2

PLEASE HELP ME!!!

    1. Where it says X rides, are you sure there is not a number there? There is not enough information in that problem the way it is written.
    2. For right triangles, use the pythagorean theorem. a^2+b^2=c^2..6^2+10^2=? Then simplify that.
    3. Use the quadratic formula: (-b+-sqrtb^2-4ac)/2a
    Post your answers if you'd like them checked.

    2a+5r=22
    2a + xr = 24
    I need to know x to solve for a and r.

    h^2 = 6^2 + 10^2
    h^2 = 136
    h = 2 sqrt 34

    x = [5 +/- sqrt(25+12)]/6
    = [ 5 +/- sqrt (37)]/6
