<span>Audible beats are formed by the interferences of two waves in which are from the slightly different frequencies which is letter a. It is because having two waves that consist of slightly different frequency causes or produce the audible beats to be formed in which they are beats that causes sound to be either loud or soft.</span>
To simplify this you need to distribute the brackets/parenthesis:
This is known as the distributive property.
This is done by multiplying the numbers encompassed by the brackets by the number to the left of the brackets.
3*b=3b
3*8=24
3b+24
This is the most you can simplify this expression.
Hope this helps!

Answer:
4m/s^2
Explanation:
mass(m)=20 kg
force=80 N
acceleration (a)=?
Therefore,
Force = mass * acceleration
80 = 20*a
a=80/20
=4m/s^2
