About 450 books and articles Euler completed after he lost his sight entirely.
<h3>Who was Leonhard Euler?</h3>
Leonhard Euler was a mathematician from Switzerland. He introduced the fundamentals of graph theory and topology.
His main field of work includes number theory, mechanics, fluid mechanics, and many more.
The life span of Euler was between 1707 and 1783. In the last few years of his life, he lost the eye sight. But the eye sight loss doesn't affect him from doing his work. In his lifespan, he published around 886 books and articles on various fields or science, mathematics and engineering.
After the total blindness, he published more than 450 books and articles.

Answer:
length= 9
width= 3
Step-by-step explanation:
x= width
length = x+6
x+6+x+6+x+x=24
4x+12=24
take 12 from both sides
4x= 12
x=3

Answer:
![y =\frac{1}{5}x+\frac{22}{5}](https://tex.z-dn.net/?f=y%20%3D%5Cfrac%7B1%7D%7B5%7Dx%2B%5Cfrac%7B22%7D%7B5%7D)
Step-by-step explanation:
To write the equation of a line, use the slope formula to first find the slope.
![m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{3--9}=\frac{3}{3+12}=\frac{3}{15}=\frac{1}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cfrac%7B5-2%7D%7B3--9%7D%3D%5Cfrac%7B3%7D%7B3%2B12%7D%3D%5Cfrac%7B3%7D%7B15%7D%3D%5Cfrac%7B1%7D%7B5%7D)
Substitute m=1/5 and the point (3,5) into point slope formula.
![y-y_1 = m(x-x_1)\\y-5=\frac{1}{5}(x-3)\\y-5=\frac{1}{5}x -\frac{3}{5}\\y =\frac{1}{5}x+\frac{22}{5}](https://tex.z-dn.net/?f=y-y_1%20%3D%20m%28x-x_1%29%5C%5Cy-5%3D%5Cfrac%7B1%7D%7B5%7D%28x-3%29%5C%5Cy-5%3D%5Cfrac%7B1%7D%7B5%7Dx%20-%5Cfrac%7B3%7D%7B5%7D%5C%5Cy%20%3D%5Cfrac%7B1%7D%7B5%7Dx%2B%5Cfrac%7B22%7D%7B5%7D)
