Hope this helped ^^
K+3=-9
k=-12 is the answer
Answer:
12 R 147
Step-by-step explanation:
This equation is not factor-able, so we can use the quadratic formula.
x=(-11+square root(11^2-4(-12*-3)))/(2*-12)
x=(-11+square root(-23))/(-24)
Since we have the square root of a negative in this equation, there are no real roots for the quadratic.
The answer is 12. All you had to do was divide.
So, 30 divided by 2.5 equals 12.
I hope this helps!
