Just drew an isosceles triangle. one side of the triangle was 5 inches long. the other side of the triangle was 8inches long

The graph represents the gallons of water in a water tank with respect to the number of hours since it was completely filled

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 24÷(-2)(3)+7 a. -29 b. 3 c. 11
