I really don’t know I’m sorry I just need to answer a question to answer mine
H=2f/m+1
subtract one from both sides
h-1=2f/m
multiply m to both sides
m*h-1=2f
divide 2 both sides
mh-1/2=F
<span>(the whole left side of the equation is divided by 2 i just cant do it on the computer)</span>
Longer wavelength means lower frequency (lower pitch)
2/3 is the answer.
<span>1/3 is equal to 33.33333333% </span>
<span>so 2/3 is equal to 66.6666666%</span>
Answer:
4b² - 16
Step-by-step explanation:
The formula to find the area of a parallelogram equals 
, where b = base and h - height. We're given the base as 2b + 4 and the height as 2b - 4.
Therefore, the answer is 4b² - 16.
