Answer:

<h3>28</h3>

Step-by-step explanation:

Area of a square =

s^2

Perimeter =

4\times s

Where s = side

Solve for s using the area

A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7

Find the perimeter

4\times s\\\\= 4 \times 7\\\\= 28

max2010maxim [7]

Answer:

The car is going 45 mph

Step-by-step explanation:

Since the speed limit is 35 mph and the car is 10 mph over the speed, we can add them to find out how fast the car is going. We can solve 35+10 which will give us 45. So it is not a sum of 0 but instead a sum of 45.
