Answer:
A) 7.24 hours
Step-by-step explanation:
The together rate is the sum of each separate rate.
In this problem:
Beth's rate is 1/15(suppose there was a small typing mistake there, with 151 none of the options are correct).
Mike's rate is 1/14
The together rate is 1/x
Then
We want to find x.
15*14 = 210. So
Cross multiplication
So the correct answer is:
A) 7.24 hours
The factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)
<h3>How to match the
polynomial?</h3>
The polynomial expression is given as:
x^2 - 3x - 18
Express -3x as 3x - 6x
So, we have:
x^2 + 3x - 6x - 18
Factorize the polynomial expression
x(x + 3) - 6(x + 3)
Factor out x + 3
(x + 3)(x - 6)
Hence, the factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)

Step-by-step explanation:
To write the equation of a circle, use the formula where the center of the circle is (h, k).
This means the equation is .
Find the radius r by dividing the diameter of 10 in 2. The radius is 5.
So the equation of the circle is
