Let
x------> the <span>length of a room
y-----> the width of a room
we know that
Area of a room=x*y
Area of a room=432 ft</span>²
so
432=x*y-----> equation 1
x=3y-----> equation 2
substitute equation 2 in equation 1
432=[3y]*y----->432=3y²
y²=432/3
y²=144----------> y=√144-----------> y=12 ft
x=3y-----> x=3*12-----> x=36 ft
the answer is
the width of the room is 12 ft
Answer:
y-y/x-x
1--1/3-4
1+1/3-4
2/-1
= -2
then you plug in with any one of the points
y=mx+b
1= -2(3) + b
1 = -6 + b
b = 1+6
b = 7
so the equation is: y = -2x+7
