3x + 3x + x + x = 98
98 / 8 = 12.25
36.75 + 36.75 + 12.25 + 12.25 = 98
Answer: 36.75
Answer: 6.9 and 10.4
Step-by-step explanation:
The perimeter of the pentagon is 10 so you can either do 10 times 1.38 times 1/2 or do 5 times 1.38 and it equals 6.9
The perimeter of the hexagon is 12 and you follow the same steps so I did 6 times 1.73 and you get 10.4
Answer:

Explanation:
The sum of two numbers is the result of when they are added up. So the "sum of the length and width" is the length + width or l + w. One-sixth of the sum of the length and width is l+w divided by 6. so you get:

Okay, are you saying:
-a = 2, b = 2, c = 2, solve (a + b + c)
or
-2a * 2b * 2c(a + b + c)
