Area of a square is its side length squared...
A=s^2 solving for s...
s=√A
The perimeter of a square is 4 times its side length...
P=4s, and since s=√A
P=4√A, and we are told that A=100 in^2 so
P=4√100
P=4*10
P=40 in
Answer:
y=-3x+14
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-26)/(6-(-4))
m=-30/(6+4)
m=-30/10
m=-3
y-y1=m(x-x1)
y-26=-3(x-(-4))
y-26=-3(x+4)
y=-3x-12+26
y=-3x+14

Answer:
Perpendicular
Step-by-step explanation:
-2x+3y=-1
6x+4y=4
----------------
3y=-1-(-2x)
3y=-1+2x
3y=2x-1
y=2/3x-1/3
-----------------
4y=4-6x
4y=-6x+4
y=-6/4x+4/4
y=-3/2x+1
--------------------
2/3 and -3/2 are negative reciprocals, therefore, they are perpendicular.
