Next time add an image, but know that the expression is equal to 657 since..
83 * 8 -7
Use PEMDAS
664 - 7
657

Answer:
17 feet
Step-by-step explanation:
Since a square has 4 sides, you have to do 68 / 4 to find one of the sides. 
68/4 = 17
And to check, if you add up all sides...
17+17+17+17 = 68
 
        
             
        
        
        
Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer:
<u>The correct answer is B. 40 mph</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Distance (d) the car traveled = 120 miles
Time (t) of the travel = 3 hours
2. What is the average rate of speed?
Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel 
Replacing with the real values, we have:
Rate of speed (r) = 120/3 miles per hour
Rate of speed (r) = 40 miles per hour
<u>The correct answer is B. 40 mph</u>
