The wheels on Kevin’s bike have a diameter of about 3 feet. How far does the bike travel in 12 complete rotations? (Use 3.14 to represent pi)

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

The suare root of 9x plus 7 plus the square rot of 2x equall to 7

Which of the following represents the length of a diagonal of this trapezoid?
