Answer:
10x - 20
Step-by-step explanation:
<em>Distribute 5 </em>to <em>each</em> of the terms within the parentheses to get 5(2x) - 5(4) = 10x - 20.
A number (X) minus 25 is equal to three.
Answer:
C
Step-by-step explanation:
We want to simplify the rational expression:

First, we can factor both the numerator and the denominator. This yields:

Cancel like terms:

However, since we canceled a term from our expression, we must place restrictions in order to stay true to the original expression.
Rational expressions are undefined whenever the denominator equals 0. The denominator is (before canceling):

Solve for n. By the zero product property:

Therefore:

By taking the square root of both sides (since we are taking an even root, it is required to have plus/minus):

Therefore, our fully simplified expression is:

Hence, our answer is C!
Take all the non-zero digits and separate them from the zeros.
Then with zeros, how many are there?
Then multiply non-zero digits and zeros in powers.
3.482 * 10^6
