X=4
First find the solution to (x+1) ft. I chose to guess the answer as 4 and it worked (you’ll have to guess). I then plugged 4 into the other equation 2x. It became 2•4. Solving give the side length of 8 ft. Then you have to check to make sure they both have the same area. To do this just solve the equations. 
First rectangle- 4•4= 16 ft area
Second rectangle- 2•8 = 16 ft area 
( I’m really sorry if this is confusing)
        
             
        
        
        
Most of the information's that are required for solving this question is already given in the question. It is important to check them minutely before trying to solve the problem in hand. 
Amount of prize money won by the darts team = 1750 pounds
The amount of money that needs to be saved = 70 pounds
Then
Amount of money remaining after savings = (1750 - 70) pounds
                                                                     = 1680 pounds
The number of  team members in the darts team = 14
So
The amount of money 
that each members of the darts team gets = 1680/14
                                                                     = 70 pounds
From the above deduction we can easily conclude that each member of the darts teams will get an amount of 70 pounds.
        
                    
             
        
        
        
Let the measure of an angle be 'x'
Then the reflex angle will be measured by the formula (360-x)
x +(360-x) = 360
        
             
        
        
        
According to the information in the nutritional table, it can be inferred that the amount of milligrams of sodium that we should consume during the rest of the day must be less than 2,175mg,
<h3>How to calculate the amount of sodium we can consume?</h3>
To calculate the amount of sodium that we can consume during the rest of the day after breakfast, we must subtract the value of sodium consumed to the amount of total sodium that we want to ingest as shown below:
According to the above, it can be inferred that after consuming the cereal bar at breakfast, we should consume an amount less than or equal to 2,175mg of sodium in the other meals of the day (lunch, dinner and snacks).
