he formula of a distance between a point (a, b)
and a line Ax + By + C = 0:

We have the point A(-1, 7) → a = -1, b = 7
and the line y = 3x → 3x - y = 0 → A = 3, B = -1, C = 0.
Substitute:

<h3>Answer: d = √10</h3>
Given the numbers above and those numbers only the mean would be 1.8
It is the area of two triangle and one rectangle
area of a triangle is 1/*b*h
A=1/2*1.9*2.8=2.66 ft^2 multiply it by 2 as we have 2 triangle= 5.32 ft^2
Area of a rectangle=w*l=3.2*2.8 =8.96 ft^2
Add them =8.96+5.32=14.28ft^2
Look at the picture.
Use the Pythagorean Teorem:
That is a G major. The hashtag means major and it is located on the in the middle of he top line.
