i believe it is 2 i took the test but it was a while ago sorry if it’s wrong!
Answer:
The first option
.
Step-by-step explanation:
To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be
. This eliminates the bottom two solutions.
In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like

This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.
Only answer choice 1 meets the requirement.
Answer:
y=6
Step-by-step explanation:
-x+2y=10
-2+2y=10
2y=12
y=6
length = area/width
l = 45/5 = 9
The length of the rectangle is 9.
