The x is the variable so you have to find what the equation equals in order too find out what variable x is. 2 x7+2 = 16. So now x = 16
1 mile = 5,280 feet.
Convert the 0.25 mile to feet:
0.25 miles = 0.25 x 5,280 = 1,320 feet.
Add the soda shop distance to this:
1,320 + 900 = 2,220 feet.
Total distance is 3 miles and 2,220 feet
The measure of arc EF = 146 degrees because its central angle = 146 degrees.
Let

be the length of the rectangle and

be the width. In the problem it is given that

. It is also given that the area

. Substituting in the length in terms of width, we have

. Using the zero product property,

. Solving these we get the width

. However, it doesn't make sense for the width to be negative, so the width must be

. From that we can tell the length

.
