This is just combining like terms.....
6n2 - 5n2 + 7n2
n2 + 7n2
=8n2
Angle BDC is given as 38° but not drawn in the figure. Amateurs.
We calculate angle DBC
DBC = 180° - 96° - 38° = 180° - 134°
We won't bother subtracting because we're really after
angle ABD = 180° - DBC = 134°
Now we have a Law of Cosines situation,
AD² = AB² + BD² - 2(AB)(BD) cos ABD
AD = √( 5.8² + 27.3² - 2(5.8)(27.3) cos 134°)
AD ≈ 31.61 m
Answer: 31.6 m
Answer:
D. 10.20 cm
Step-by-step explanation:
If you would like to solve x^5 * x^4 * x^3, you can do this using the following steps:
<span>x^5 * x^4 * x^3 = x^(5 + 4 + 3) = x^12
</span>
The correct result would be x^12.
