Answer:
Step-by-step explanation:
Since the angles are equal the equation to solve would be:
you will subtract 3x from 5x and get 2x
subtract 20 from 50 to get 30
divide each side by 2
Hope this helps
Im gonna assume you are solving for x, the equation (x + 3)2 = 49 x is equal to 21.5 or 21 and 1/2. however the rest aren’t equations they’re just x = number and there isn’t much to do with that
Most likely cot x = cos x / sin x , but i'm still learning this myself. I hope it helps :)
The number of cows is given by
So, after years, the number of cows will be
We want this number to be twice as much as the original:
First of all, we can cancel 14 from both sides:
Finally, on the right hand side, we can use the exponent rule
to get
To solve this equation, we must impose that the two exponents are the same:
And clearly this is true if and only if . So, it will take 5 years for the cow heard to double in number.
You can do the exact same steps to find the doubling time for the sheeps.
Yea .........., the answer is B.
