Answer:
Option (3)
Step-by-step explanation:
In a right triangle,
Cosine rule → 
Sine rule → 
In the given triangle,
By cosine rule,
Or cos(h°) = z ÷ x
Therefore, Option (3) will be the answer.
The answer is 77. if you do it the opposite way and multiply
C. The product of a constant factor of six and a factor with the sum of two terms. In this case, 6 is constant, and the sum of two terms is: y+3. Since they are products, you multiple them. Therefore C would be correct.
The least (or lowest) common denominator of 3, 16 and 8 is 16. That already points us to answer A.
Checking for each fraction:
1/2 * 8/8 = 8/16
3/16 * 1/1 = 3/16
7/8 * 2/2 = 14/16
Yep. Answer A.
The answer is 10x^4 - 2x ^3
