Please help put the solution if you can

Z = 23

Step-by-step explanation:

We know that LNM is congruent to XYZ and we know that all the angles add up to 180 degrees. We have 2 angle measures. 124 and 33 so we add these up and get 157. Subtract 157 from 180 and we are left with 23 as Z.

Correct E

Explanation:

E. Given that the equation x2+ mx+ n= 0 has two solutions, x = kand x = 2k,you can work backward to build the original equation. Here’s how:

x= kx= 2k

x– k= 0 x– 2k= 0

Now take the two equations and combine them:

(x– k)(x– 2k) = 0

x2– 2kx– kx + 2k2= 0

x2– 3kx + 2k2= 0  

As you can see, m= –3kand n = 2k2, so mn= –6k3.
