The first step for solving this expression is to write the division as a fraction.
x +

× x
Calculate the product.

Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:

Now multiply the terms with the same base by adding their exponents.

Finally,, add the numbers together to get your final answer.
x +

Answer:
14 - 13x
Step-by-step explanation:
take 13x + 1 away from 15
15 - (13x + 1) = 15 - 13x - 1 = 14 - 13x
Answer:
The wavelength, of a sound wave with a frequency of 20 waves per second is 15,000,000 m.
Step-by-step explanation:
In this question, we have to calculate the wavelength of a sound wave of frequency 20 waves per second.
We know that the speed of light in air/ vacuum is
.
Now by the formula v = nλ , where v = speed of light in air/vacuum, n = frequency of the wave and λ = wavelength in meters,
we put the values
= 20 × λ
λ = 
λ = 15,000,000 m
