Answer: An undersupply of serotonin is most closely linked to <em>depression</em>.

The correct answer is D; depression.

Explanation:

Serotonin is a naturally produced chemical in the human body. When the body is not producing serotonin a person can start having numerous symptoms. One of the symptoms is depression. This chemical is also known as the "happy chemical" since it affects the mood, happiness, and a person's overall well being.

When the body isn't producing this chemical, people may become hungry and crave sugar, they may have issues with being hot or cold all the time, and have trouble sleeping.

To raise serotonin levels there are several things that can be done. a few of these things are; taking a walk in the sunshine, changing your diet, get a good night's sleep, take vitamin D, and try to lower stress in your life.

mash [69]

Answer:

9 {x}^{2}  + 42x + 49

Explanation:

(3x + 7)(3x + 7)

=  >  {(3x + 7)}^{2}

Using the algebric identity{(a + b)}^{2}  =  {a}^{2}  +  {b + 2ab}^{2}

So,

{(3x + 7)}^{2}  =  {(3x)}^{2}  +  {(7) }^{2}  + 2 \times 3x \times 7

=   9 {x}^{2}  + 42x + 49
