Answer:
Assuming that the notation there is meant as:

then the answer would be 1/(9c²)
If the -2 is indeed just subtraction and not an exponent, then it is simply 3c - 2
Answer:
so 24 is the answer
Step-by-step explanation:
first 1/4 is 20 out of 60
Second, we have to work out one fifth. The easiest way to do this is to divide 60 by five.
60 divided by 5 = 12
(We should know this from our times tables, 5x12=60)
We then times the fifth by three to work out three fifths.
12 x 3 = 36
We can then check this by working out two fifths and checking that both the answers add up to make 60.
We work out two fifths the same way we work out three, timesing by the value for one fifth.
12 x 2 = 24
24 + 36 = 60
So we know that we were correct and our final answer is
3/5 of 60 = 36.
then 24 + 36 = 60
so 24 is the answer
I believe it is 15. It is a scalene triangle.
Since 85 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 85?" will have an infinite number of decimals.
Hi there!
Let's solve this equation step by step!

First work out the parenthesis, which can for instance be done using rainbow technique.

Subtract 2u from both sides.

Subtract 38 from both sides.

And finally divide both sides by -6, in order to isolate the variable u. Remember that dividing a negative by a negative gives a positive outcome.

Hence, the answer is u = 9.
