Answer:
7n + 5 − 9n = 8 − 2n − 3 = true
-2 n + 5 = 5 - 2 n = true
Step-by-step explanation:
Left-hand side:
Simplify the following:
7 n - 9 n + 5
Grouping like terms, 7 n - 9 n + 5 = 5 + (7 n - 9 n):
5 + (7 n - 9 n)
7 n - 9 n = -2 n:
Answer: -2 n + 5
____________________________
Right-hand side:
Simplify the following:
-2 n - 3 + 8
Grouping like terms, -2 n - 3 + 8 = (8 - 3) - 2 n:
(8 - 3) - 2 n
8 - 3 = 5:
Answer: 5 - 2 n
Answer:
C. 6.19 mi
Step-by-step explanation:
The angle between the two ship locations as viewed from the lighthouse is ...
23° -14° = 9°
This is opposite the known side of the triangle: 4 miles. The unknown side, the distance to the lighthouse from the second position, is opposite the 14° angle in the triangle. The Law of Sines can be used to find the distance (d) of interest:
d/sin(14°) = (4 mi)/sin(9°)
d = (4 mi)(sin(14°)/sin(9°)) ≈ 6.1859 mi
The ship is 6.19 miles from the lighthouse at the second sighting.

This is the population 7 years after 2002(2009)
Step-by-step explanation:
<h3>
<em><u>Given</u></em><em><u>:</u></em></h3>
Length of the rectangle = 6.5 m
Width of the rectangule = 7.3 m
<h3>
<em><u>Then</u></em><em><u>:</u></em></h3>
<u>First</u><u> </u><u>case</u><u>,</u>
Area of the rectangle
= length × width
= 6.5 m × 7.3 m
= <em><u>47.45</u></em><em><u> </u></em><em><u>s</u></em><em><u>q</u></em><em><u>.</u></em><em><u>m</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em><em><u>(</u></em><em><u>i</u></em><em><u>)</u></em>
<u>Second</u><u> </u><u>case</u><u>,</u>
Perimeter of the rectangle
= 2(length + width)
= 2(6.5 + 7.3)m
= 2 × 13.8 m
= <em><u>27</u></em><em><u>.</u></em><em><u>6</u></em><em><u> </u></em><em><u>m</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em><em><u>(</u></em><em><u>ii</u></em><em><u>)</u></em>
