can someone tell me if i did the problem correct (solve by completing the square) 4x^2+2x3=0 x^2+(1/2)=3/4 x^2+(1/2)+(1/4)^2=3/4+(1/4)^2 (x+1/4)^2=13/16 x+1/4=+sqrt 13/16 x+1/4=+sqrt 13/4 x=1/4+sqrt 13/4 x=1+sqrt 13/4

Solve for s: h=(square root of 3)times s/2 and solve for h V= (pi)r squared h / 3 Solve for s: h=(square root of 3)times s/2 Multiply both sides by 2. 2h = (sqrt 3)*s*2/2 which cancels the 2 on the right. 2h = (sqrt 3)*s Now
