The gradient of the perpendicular line would be the negative reciprocal of the original line. Therefore the gradient of the perpendicular line would be -2/5x.
Since we know y=mx+c, ∴y=-2/5x+c. Sub in the x and y values of the given point and we get that c=26/5.
The perpendicular equation would be y=-2/5x+26/5.
I hope I got this right.

Step-by-step explanation:
that don't make no sense
Let n = length
let n-4 = width since it is 4 meters shorter
2( n+n-4) =72 Two of the length and width added together equal the perimeter
combine like terms
2(2n -4) = 72 Now use the distributive law on the left side of the equation
4n -8 = 72 Now add 8 to both sides
4n -8 +8 = 72 +8
4n = 80 Finally divide each side by 4
n=20
so the length is 20 and the width is 4 less or 16.
Let's see if our answer works.
20 + 16 + 20 +16 =? 72
72 =72 yes, it does. Length = 20 Width = 16

Step-by-step explanation:
Answer:
the pattern step number of second step is added to number of balls used of first step to get number of balls used of second step
that is
1 + 2 ( number of balls added to pattern step number) = 3 (number of balls used)
in the same way
6 + 4 = 10 ( first blank )
5 + 10= 15 ( second blank)
15 + 7 = 22 ( third blank )
22 + 8 = 30 ( fourth blank)
