Answer:
3
Step-by-step explanation:
As the CD line is parallel to x-axis hence the separation or length is measured on the x-axis i.e.
the length of CD = length of C - length of D = 7 - 4 = 3
The value of n to the nearest whole number is 22
<h3>Trigonometry</h3>
From the question, we are to determine the value of n to the nearest whole number
In the diagram,
The given triangle is a right triangle.
Thus,
Using the <em>Pythagorean theorem</em>, we have that
n² = h² + k²
∴ n² = 9² + 20²
n² = 81 + 400
n² = 481
n = √481
n = 21.93
n ≈ 22
Hence, the value of n to the nearest whole number is 22

The first part of the answer can be found by finding the GCF between 15 and 25. 15 is divisible by 1, 3, 5, and 15. 25 is divisible by 1, 5, and 25. You can see that their GCF is 5. Next, you need to look at the variables. The first monomial has a, b, and

. The second monomial has

, b, and c. They each have at least one a, one b, and one c, so those will be in the GCF (abc). If you put that together with the 5, you get that the GCF is
5abc.
