Can i get some on how to do this? write the conditional statement that the venn diagram illustrates

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 square pyramid has a volume of 441 cubic inches. what is the value of x? 1/7x is the height x is the base

What is 1/3x5 on anuber line what does it look like on a number line
