Answer:
The fraction of the area of ACIG represented by the shaped region is 7/18
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
In the square ABED find the length side of the square
we know that
AB=BE=ED=AD
The area of s square is

where b is the length side of the square
we have

substitute


therefore

step 2
Find the area of ACIG
The area of rectangle ACIG is equal to

substitute the given values

step 3
Find the area of shaded rectangle DEHG
The area of rectangle DEHG is equal to

we have 

substitute
step 4
Find the area of shaded rectangle BCFE
The area of rectangle BCFE is equal to

we have


substitute

step 5
sum the shaded areas

step 6
Divide the area of of the shaded region by the area of ACIG

Simplify
Divide by 5 both numerator and denominator

therefore
The fraction of the area of ACIG represented by the shaped region is 7/18
Answer:
5+6-3=8
Step-by-step explanation:
The question is asking which of the following does not have side that are parallel. So which of them have lines that would never touch if they were never ending lines.
2n + 1 et 2n + 3 are two odd integers with n integer
(2n+1)(2n+3) = 4n² + 8n + 3 =2(4n² + 4n) + 3
2(4n² + 4n) is an even integer so 2(4n² + 4n) + 3 is an odd number
because the sum of an even number and an odd number is an odd number.
