Answer:
36 tiles
Step-by-step explanation:
First, find area of the square floor knowing the formula as;
Area=
where s= side of a square.
If one side of the floor is 12 feet, then Area=
Next, find the area of each tile using the same formula and given s=2 feet;
Area(tile) =
To find the number of tiles needed to cover entire floor, divide area of the floor by area of one tile; 144 / 4 = 36 tiles
Answer:
The system has no solution
Step-by-step explanation:
we have
----> equation A
isolate the variable y
Divide by 3 both sides
----> equation B
Compare equation A and equation B
Their slopes are equal and their y-intercepts are different
Remember that
If two lines have the same slope, then the lines are parallel
In this problem we have two different parallel lines, so, the lines don't intercept
therefore
The system has no solution
