Answer:
Step-by-step explanation:
The measure of the floor of the rectangular room that is 12 feet by 15 feet. The formula for determining the area of a rectangle is expressed as 
Area = length × width
Area of the rectangular room would be 
12 × 15 = 180 feet²
The tiles are square with side lengths 1 1/3 feet. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet
Area if each tile is 
4/3 × 4/3 = 16/9 ft²
The number of tiles needed to cover the entire floor is 
180/(16/9) = 180 × 9/16
= 101.25 
102 tiles would be needed because the tiles must be whole numbers.
 
        
             
        
        
        
Answer:
2x² + 7x + 6
Step-by-step explanation:
To solve this polynomial, you need to distribute/multiply, (x+2) with (2x+3).
You would first multiply (x) with 2x and 3. This would give you 2x² and 3x. You would then multiply 2 with 2x and 3. This would give you 4x and 6. You then add the like-terms, which are 3x and 4x, which gives you 7x. This would give you your final expression of 2x² +7x + 6.
(x+2)(2x+3)
2x²+ 3x + 4x + 6
2x² +7x + 6
 
        
                    
             
        
        
        
Answer:
JK=  3 in
Step-by-step explanation:
There is a theorem that says that the angle of a tangent and the radius is of 90°
so we can use the pythagora's theorem

 
        
                    
             
        
        
        
Answer:
-30/15 or -2
Step-by-step explanation:
2+8 = 10
3+2 = 5
14-2 = 12
4-1 = 3
10/5 - 12/3
(Find GCF)(GCF = 15)(5 times 3)
30/15 (10/5 times 3)
60/15 (12/3 times 5)
30/15 - 60/15 = -30/15 --> -2(simplified to 2)
