n times 4, n being a number of notebooks, would equal c, or the overall cost.
The interior angle of a regular octagon is 135 degrees.
<h3>What is an octagon?</h3>
An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.
Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.
Therefore,
n = number of sides = 8
Hence,
interior angle = (n - 2)180 / n
interior angle = (8 - 2)180 / 8
interior angle = 6 × 180 / 8
interior angle = 1080 / 8 = 135°

Answer:
A, C, E
Step-by-step explanation:
The square root of 10 is approximately 3.16, which is greater than pi which is equal to about 3.14, which shows that C is correct as well. The square root of 11 is 3.31, and the square root of 5 added to the square root of 6 is equal to about 3.69, which is greater than the square root of 11.
4(2x+5)-8 = 36
8x+20-8 = 36
8x = 24
x = 3
