First add the whole numbers;
5 + 3 = 8
then add the numerators( you could add them cause they have like denominators);
8/12 + 5/12 = (8+5) = 13/12
13/12 = 1 1/2
so your final answer would be: 9 1/2 (I added the whole numbers)
It would be 12(4x+6). This can also be represented as 48x + 72.
The side of the square = 16 in
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle.
So, the diameter of the circle is equal to 16 in => radius = 8 in
Circumference = 2πr = 2π8 = 16π = 50.24
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.
