<h3>☂︎ Answer :- </h3>
<h3>☂︎ Solution :- </h3>
- LCM of 5 , 18 , 25 and 27 = 2 × 3³ × 5²
- 2 and 3 have odd powers . To get a perfect square, we need to make the powers of 2 and 3 even . The powers of 5 is already even . 
In other words , the LCM of 5 , 18 , 25 and 27 can be made a perfect square if it is multiplied by 2 × 3 . 
The least perfect square greater that the LCM , 
☞︎︎︎ 2 × 3³ × 5² × 2 × 3 
☞︎︎︎ 2² × 3⁴ × 5²
☞︎︎︎ 4 × 81 × 85
☞︎︎︎ 100 × 81 
☞︎︎︎ 8100 
8100 is the least perfect square which is exactly divisible by each of the numbers 5 , 18 , 25 , 27 . 
 
        
        
        
Answer:
7(7x -4)
Step-by-step explanation:
49x-28
We can factor a 7 from each term
49x = 7*7x
28 = 7*4
7(7x -4)
 
        
             
        
        
        
Answer:
Radius: 7
Diameter: 14
Area Formula: π r^2
Area Answer: 154 ft^2
Step-by-step explanation:
Radius: 14/2 = 7
The radius is always half the diameter.
Area Work
A = π(7)^2
A = π(49)
A = 153.9380 ft^2
 
        
             
        
        
        
1 unit to the left of -1 on the number line is -2.
Thus, 7 units to the left of -1 is -8.
The appropriate choice is ...
... c. -8
