the sum of all interior angles in a polygon is
180( n - 2)
n = number of sides
now, this polygon is a quadrilateral, so it has 4 sides, so it's total is just 180( 4 - 2) = 360.

3a+7+2a and 7a+5. These expressions are not equivalent. 5a+7 does not equal 7a+5.
This is the inverse of f(x)= -3 - (-2)
First, multiply 50*3 to get the answer in feet which is 150 ft.
Then, divide 150 ft by 60 which would be 2.5 ft per second.
