So to find the discriminant of a quadratic equation, the formula is b² - 4ac with a = x² coefficient, b = x coefficient, and c = constant. In this case, our equation is 
Firstly, solve the multiplications and the exponents: 
Next, subtract and we find that our discriminant is 0.
*Additional Info: Since the discriminant is zero, this means that this quadratic equation has 1 real solution.
Answer:
11cm = diameter.
c=circumference
d=diameter
π=3.14
r=half of diameter
34.56
C=2πr
d=2r
Solving for d (diameter)
d=C
π=34.56
π≈11.00079cm
rounded = 11cm!

Step-by-step explanation:
If you multiply 4 by 4 tenths, the answer is 1.6
tenth = 0.1
four tenths = 0.4
4(0.4) = 1.6
Answer:
-8/3 or -2.66666 or -2 2/3
Step-by-step explanation:
Move constant (+9) to the right side and change its sign (25 - 9)
Then subtract those numbers (=16)
Divide both sides by -6
