Answer:
D
Step-by-step explanation:
We know it has 2 distinct zeros. This means the discriminant of the quadratic is positive and must have 2 real zeros that can be rational or irrational. We also know the quadratic has rational coefficients which means both are either rational or irrational. They can not be one of either. Since it tells us one is rational, the other must be too.

the awnser is 9 seconds
Step-by-step explanation:
132÷11=12
12 cm per second

9 seconds
Answer:
Given the information, the value of x is 20.
Step-by-step explanation:
For this problem, we have to find the ratio between the line segments in order to find the value of x.
We are already given two line segments that we can find the ratio for. We are given 30 and 12. In order to find the ratio, then we must divide 12 by 30.
12 ÷ 30 = 0.4
Now that we have our ratio, we can now divide 8 by 0.4 to find the value of x.
8 ÷ 0.4 = 20
So, the value of x is 20 which is the third answer choice in the problem.
54/6 = 9.
Vol= 9 x 3 = 27cm^3.
