Penelope is making a quilt that has 4 section, each of which is 2 5/8 feet in length. what is the length of the entire quilt? a- 2 3/8 ft. b- 6 5/8 ft. c- 7 7/8 ft. d- 10 1/2 ft.

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

Simplify using positive exponents only.
