3(6-4x)-27x+10x-31 =
18-12x-27x+10x-31 distributed. =
-13 - 29x
Cos (Angle) = Adjacent leg / hypotenuse
Cos(68) = Adjacnet leg / 12
Adjacent leg = cos(68) * 12
Adjacent leg = 4.495 feet. Round the answer as needed.
Answer:
Step-by-step explanation:
We have the equation:
Let's simplify this a bit. Let . Then . We can substitute the exponents:
Use the properties of exponents, we can write . We can do the same thing on the right. So:
We can now factor out a from the left and a on the right. This yields:
Evaluate the expressions within the parentheses:
Evaluate:
Now, let's multiply both sides by . So:
Also, let's divide both sides by . Multiply on the right:
Therefore:
We can now substitute back u. Notice that 27 is the same as 3 cubed and 1000 is the same as 10 cubed. So:
Since they have the same base, their exponents must be equal. Therefore:
Add 2 to both sides:
So, the value of x is 5.
And we're done!
Answer:3

Answer:
The answer is A
Step-by-step explanation:
The ones that start with y are not the answer because the ellipse is not vertical and option b is wrong because you have to subtract h and k not add them.
