You need to order carpet for a room that has a length that is three times its width. if the area of the room is 432 square feet,
find the width of the room.
1 answer:
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

Step-by-step explanation:
(2, -3) is in the 4th quadrant. By the counter clockwise rotation of 90° around the origin, it will be in the 1st quadrant.
Any point in the 1st quadrant has both positive x and y coordinates.
So the answer is (3, 2).
Answer:
-1 < x
Step-by-step explanation:
-10 < x - 9
+9. +9
-1 < x
Y = a(b^x)
y=mx + b is the equation of a line. It is a linear function because it has a constant rate of change.
y = a(b^x) is an exponential function because it has has an exponent and its rate of change is not constant
Answer:
x=-11
Step-by-step explanation:
-9x-4-8+7x=10
-2x-12=10
+12 +12
-2x=22
-2x/-2=22/-2
x=-11
