Umm... hey ppl i have to show my this sketch to my friends, so do you think they will like it ?​

Fractions can be added and subtracted only if they're fractions. a. like b. proper c. improper d. unlike

In the diagram, the ratio of ab to ae is (1/2) . what is the ratio of the length of to the length of ?

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
