Step-by-step explanation: 
1. x> = - 3 
2. x <= - 3 
Isolate the variable by dividing each side by factors that don't contain the variable

Answer:
Step-by-step explanation:
2⅝ miles/(3½ minutes) = (21/8 miles)/(7/2 minutes) = ¾ mile/minute
d = ¾m = 0.75m
 
        
             
        
        
        
So, we know the perimeter is 24 cm. and the top part is the left part, (x) + 2, but remember, we need to have it be a number that, multiplied by 2, is 24. So, using this formula, the length, (top / bottom) is 7, and x = 5. Because 5 + 5 = 10, and when length is +2, it adds up to 14. 10 + 14 = 24. So, length is 7, width, (left, right) is 5.
