At first you have to write the variables out which are

now you have to combine like terms


now you add these two variables and end up with answer of
Answer:
A vibrating object produces sound waves. Energy needs to be transferred from the vibrating object to the ear through a medium..
Explanation:
Sound is transmitted through sound waves and waves transfer energy from the source of the sound to it environment in a pattern of disturbance and travels through a media. Sound waves carry energy parallel to the motion of the wave .
Since sound involve sound wave and energy as seen in the above explanation. We can not agree with Geneva given that in order for sounds to be heard, the sound wave produced by a vibrating object needs to travel from the vibrating object to the ear through a medium as a result of radio frequency signals that are leaking into our air causing them to bounce,reflect, enabling them to be heard in the human hearing range.
The correct answer for above statement is;
True:
Explanation:
A wave-cut platform is the level area created by wave erosion as the waves threaten a cliff. An arch is designed when waves erode over a cliff. When a sea arch collapses, the insulated towers of rocks that remain are identified as sea stacks.
I really would think something besides the question
