Answer:
Option C. positive
Step-by-step explanation:
we know that
If the discriminant of a quadratic function is positive, then the quadratic function has two real solutions
If the discriminant of a quadratic function is zero, then the quadratic function has one real solution
If the discriminant of a quadratic function is negative, then the quadratic function has two complex solutions
In this problem
The quadratic function has two real solutions (x-intercepts)
therefore
The discriminant is positive
Answer:
30, 10
Step-by-step explanation:
length=x
wdith=y
xy=300, x=3y
replace x with 3y in the first equation to get
3y^2=300
y^2=100
since you cant have a negative side of a garden, y=10. x=30.
A)
Kim's age=k
Sister's age=s
k=2s
k+s=36
b)
k=2s
k+s=36
k=36-s
2s=36-s
3s=36
s=12
12*2=24
Kim is 24 and her sister is 12
