Answer:
309in²
Step-by-step explanation:
Area of an octagon is expressed as;
A=2(1+√2)a²
a is the side length of the octagon
Given
a = 8
Substitute into the formula
A = 2(1+√2)(8)²
A = 2(1+√2)(64)
Expand
A = 2(64+64√2)
A = 128+128√2
A = 128+128(1.414)
A = 128+181.01
A = 309in²
Hence the area of the octagon is 309in²
Circumference of circular path=pi*d^2/4
=44.156
length of light=1.45
light needed=44.156/1.45
=31 approx
Actually its false
In algebra 4x and 4x² are two different terms and are not like terms.

You add the two numbers and divide by two to get their average, of the number that would be midway (also a midpoint for visualization) between them. Find the least common denominator, which should be 9. Thus, you will multiply both the numerator and denominator of 7/3 by 3 to retain the ratio. You should get 21/9. Now, add 21/9 and 5/9 to get 26/9. That should be your answer, but make it a mixed number so you don't have an improper fraction.
