Answer:

3n\cdot 3n.

Step-by-step explanation:

We have been given an expression (3n)^2. We are asked to write our given expression without exponents.

Since 3n is raised to second power, this means that 3n is multiplied by itself.

(3n)^2=3n\cdot 3n

Therefore, our required expression would be 3n\cdot 3n.

I don't know how to do this. Any help?
Brut [27]

Answer:

cos 37=x/b (second one)

sin 37= a/b (third one)

tan 37=a/x (sixth one)

Step-by-step explanation:

Cos is defined by the adjacent side over the hypotenuse. Cos 37 would be x/b. Clearly, that is option 2. Sin is defined by opposite over hypotenuse. Sin 37 would be a/b. That is the 3rd option. Tan is defined by opposite over adjacent. Tan 37 would be a/x or the 6th option.

The range would be $14.

To find the range, you would take the highest value and subtract it by the lowest value:
29 - 43 =
