Answer:
I don't see a correct answer. See below.
Step-by-step explanation:
Thanks for clarifying the question. But if 27√3 is the correct expression, I don't see an answer option that fits.
√3 = 1.732
27*(1.732) = 46.77
But all the answer options are whole numbers. The presence of√3 makes it difficult to find an expression that would result in a whole number. Expressions such as:
27/√9 = 9, or
√27/√3 = 3
would be more consistent with producing a whole number result.
I hope this helps.
You combine like terms.
-2x+9x
whatever answer that is you then combine the like terms -9+-1 the you just make an expression out of them.
You can determine the speed of the car since you have the distance in half an hour. You have distance and time, so you can find speed.
Hope this helped!
Good Luck!
