Perimeter is sum of all the sides.
SO, perimeter of that triangle will be 
1/4 + 1/4 + 3/8. 
The LCM of denominators (4,4,8) = 8.
Hence writing 1/4 = 2/8.
so,
Perimeter = 2/8+2/8+3/8 = (2+2+3)/8 = 7/8.
So, 7/8 ft is the perimeter of that triangle. :)
        
                    
             
        
        
        
Rectangle B because and enlargement is when the dimensions of a shape are dilated by the same scale factor. if you multiply 5 an d6 by 3 you get 15 and 18 which are the dimensions of rectangle B
 
        
             
        
        
        
Answer:
$4
Step-by-step explanation:
Total expenditure is $55
Breakdown
2 books cost $10
4 books cost $25
Subtotal for 6 books is 10+25=$35
Remaining amount from total is 55-35=$20
If each book costs approximately $5 then for $20, each book is 20/5=$4
 
        
             
        
        
        
Answer:
The answer is A
Step-by-step explanation:
y = mx + c
m = 1/2
(2,-3)
y = (1/2)x + c
-3 = (1/2)(2) + c
c = -4
y = (1/2)x - 4
 
        
             
        
        
        
21 because it is being multiplied
