Answer:
 C. 2:5
 
Step-by-step explanation:
Find perimeter of each...
a. 10+25+21.5=56.5
b. 4+10+8.6=22.6
b:a
22.6:56.6
simplify
11.3 will go into both for..
2:5
 
        
             
        
        
        
If you are graphing quadratic equations of the type
ax^2 + bx + c = 0
The equation will look like a "U" <span>if "a" is positive </span>or it will look like an upside-down "U" <span>if "a" is negative </span>
        
             
        
        
        
Since 6x - 44 and 88 degrees are the same (exterior angles), we can start off with the first equation, 6x - 44 = 88
6x - 44 = 88
     +44    +44
6x      =   132
÷6         ÷6
x  = 22
same with the second problem (exterior angles are equal):
equation:
15x + 6 = 9x + 54
        -6              -6
15x    = 9x + 48
-9x      -9x
6x   =    48
÷6         ÷6
x   =   8
Hope this helped! :D

Answer:
The perimeter is 37 inches (3 ft. 1 in.)
Step-by-step explanation:
24 + 13 = 37
12 x 2 = 24
6.5 x 2 = 13
