We want to convert this equation in terms of m, where 
While solving this problem, I instantly noticed the 
in the first term of the equation. Replace that with m.
Simplifying the rest is not as obvious. Using the distributive property, we can change ![[7x^2+21]](https://tex.z-dn.net/?f=%5B7x%5E2%2B21%5D)
to ![[7(x^2+3)]](https://tex.z-dn.net/?f=%5B7%28x%5E2%2B3%29%5D)
Do you see the "m" in here? Look again if you don't.
Now we can simplify the equation to 
and this cannot be simplified further.
I'm always happy to help someone who appreciates the help! :D
Answer:
6 : 5
Step-by-step explanation:
Rate = 
But Rate is also equal to number of lawns mowed in a certain amount of time.
Since ratio should always be in terms of simple whole numbers.
If 6/5 lawns are mowed in 1 hour, then,
6 lawns will be mowed in:
=
= 5 hours.
therefore, 6 laws will be mowed in 5 hours.
Ratio of lawns to hours in 6:5
Sin = opposite/hypotenuse
cos = adjacent/hypotenuse
They are the same when opposite equals adjecent.
This only occurs when the angles are equal.
Answer: 45°
Step-by-step explanation:
En álgebra, una ecuación cuadrática es cualquier ecuación que se puede reorganizar en forma estándar como ax ^ {2} + bx + c = 0 donde x representa una incógnita, y a, byc representan números conocidos, donde a ≠ 0. Si a = 0, entonces la ecuación es lineal, no cuadrática, ya que no hay término ax ^ 2.
Answer: A. (4/8)
Step-by-step explanation: If there is 4 black swans and 8 swans in total you could see it's 4 black swan out of 8 total swans. You could do
8/8 - 4/8 = 4/8 to find out the answer too.
