2x²-5x+8=0
use the quadratic formula, x=(5+√39i)/4 of x=(5-√39i)/4
looks like the second choice is correct.
Answer:
The value of 
Step-by-step explanation:
We have given 
d=1.7
We have to find 
So,
from the formula

When n=14




Using the formula:

When n=26
![s_{26}=\frac{26}{2}[2(-18)+(26-1)(1.7)]](https://tex.z-dn.net/?f=s_%7B26%7D%3D%5Cfrac%7B26%7D%7B2%7D%5B2%28-18%29%2B%2826-1%29%281.7%29%5D)
On simplification we get:

Answer:
D
Step-by-step explanation:
You are given two complex numbers -i and 2+i.
For the complex number z=x+iy, the ordered pair (x,y) represents this complex number on the coordinate plane.
So, the numbers:
is represented by the ordered pair (0,-1)
is represented by the ordered pair (2,1).
Plot these two points on the coordinate plane and coonect them with a straight line. You'll get the last option of graph.
Well since she's trying to get 2 trays of equal cookies you subtract like how much does 27 go into 36 once so that's how much on each tray 27
