which means

which in turn means the next two terms are

and
![a_3=-8](https://tex.z-dn.net/?f=a_3%3D-8)
.
Im not sure what this is, or how to answer it
Answer: If two pair is parallel then it has no solution.
Step-by-step explanation:
Since we have given that
Let the number of gained yards by each player be y
For the case of Brayden:
Equation will be
![y=5x-1\\\\y-5x=-1](https://tex.z-dn.net/?f=y%3D5x-1%5C%5C%5C%5Cy-5x%3D-1)
For the case of Howard :
Equation will be
![y=5x+1\\\\y-5x=1](https://tex.z-dn.net/?f=y%3D5x%2B1%5C%5C%5C%5Cy-5x%3D1)
For the case of Vincent :
![y=4x+5\\\\y-4x=5](https://tex.z-dn.net/?f=y%3D4x%2B5%5C%5C%5C%5Cy-4x%3D5)
Since First two equations are parallel so it has no solution.
Reason:
![y-5x=1\\\\y-5x=-1\\\\\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}\\\\\frac{1}{1}=\frac{5}{5}\neq \frac{1}{-1}](https://tex.z-dn.net/?f=y-5x%3D1%5C%5C%5C%5Cy-5x%3D-1%5C%5C%5C%5C%5Cfrac%7Ba_1%7D%7Ba_2%7D%3D%5Cfrac%7Bb_1%7D%7Bb_2%7D%3D%5Cfrac%7Bc_1%7D%7Bc_2%7D%5C%5C%5C%5C%5Cfrac%7B1%7D%7B1%7D%3D%5Cfrac%7B5%7D%7B5%7D%5Cneq%20%5Cfrac%7B1%7D%7B-1%7D)
Hence, if two pair is parallel then it has no solution.
The child is <u>59.4 inches tall</u>, assuming the length from the coach's shoulder to his head cap is approximately 10 inches.
<h3>What is Heigth?</h3>
Height refers to the vertical distance between the top and bottom of something.
Height measures the length of some objects or persons vertically to determine whether it is high or low, according to some ascertained criteria.
<h3>Data and Calculations:</h3>
Baseball coach's height = 70 inches
Coach's shoulder to head = 10.6 inches
Height of the child standing slightly below the coach's shoulder = 59.4 inches (70 - 10.6)
Thus, the child standing slightly below the coach's shoulder is 59.4 inches tall.

The <em>echo</em> number 20222022202220222022 is the <em>perfect</em> square of 4496890281.
<h3>What echo number is a perfect square</h3>
An <em>echo</em> number has a <em>perfect</em> square if its square root is also a <em>natural</em> number. After some iterations we found that <em>echo</em> number 20222022202220222022 is a <em>perfect</em> square:
![\sqrt{20222022202220222022} = 4496890281](https://tex.z-dn.net/?f=%5Csqrt%7B20222022202220222022%7D%20%3D%204496890281)
