Answer: the actual length and width of the room is 24ft by 36ft
Step-by-step explanation:
The scale on the architectural plans for a new house is 1 in. equals 4 ft. This means that every 1 inch on the on the architectural plan represents 4 feet on the actual building.
Therefore, if the length of the room as measured on the drawing is 6 inches, the actual length of the room will be
6 × 4 = 24 feet
Also, if the width of the room as measured on the drawing is 9 inches, the actual width of the room will be
9 × 4 = 36 feet
The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is 
Step-by-step explanation:
We need to find a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3.
If -1, 1 and 3 are real zeros, it can be written as:
x= -1, x= 1, and x = 3
or x+1=0, x-1=0 and x-3=0
Finding polynomial by multiply these factors:

So, The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is

Answer:
alternate exterior angle
Step-by-step explanation:
the angles are on the opposite side and on the exterior of the transversal. One is on the top side of the exterior and the twelve is on the bottom side of the exterior so thats why its an exterior angle. The reason why it is alternate is because its on opposite sides of the lines
