Answer:
Step-by-step explanation:
To solve the given quadratic equation 
you can apply the Quadratic formula, which is shown below:
Where:
Therefore, when you substitute values into the Quadratic formula shown above, you obtain the following solution:
We have the following expression:
(27a ^ 3-1) / (9a ^ 2-6a + 1)
Rewriting we have:
(27a ^ 3-1) / (9a ^ 2-6a + 1)
(27a ^ 3-1) / ((3a-1) * (3a-1))
We exclude the values that make the denominator zero:
3a-1 = 0
a = 1/3
Answer:
a valid exclusion for the algebraic fraction is:
c. a ≠ 1/3
Yes. If you can express it as a fraction (=ratio) then it is rational. 0.8 is the same as 8/10.
Hello,
Alright so we are looking for a number that is ten thousand less than 842,719, so first of all, identify the place values and find the "ten thousands" place value. The nimber that is in the "ten thousands" is 42, 719 so we need to subtract 10, 000 from 42, 719. Easy either use a calculator, mental math or subtract.
42,719-10,000=32, 719
Answer:
$73
Step-by-step explanation:
Multiply 7 and 7 to get 49. Next, multiply 6 and 4 to get 24. The museum is free for the 3 children so you do not have to do anything. Add 49 and 24 to get 73, which is the price for the Baker Family.
