Since a stop sign is an octagon it has eight sides. So the perimeter will be:
p=8x, p=perimeter and x=side length. We are told that the perimeter is equal to:
16x^2-80x so we can say:
16x^2-80x=8x subtract 8x from both sides
16x^2-88x=0 factor out 8x
8x(2x-11), since we know x>0
x=11/2
x=5.5 units
Answer:

Step-by-step explanation:
The total length of this line is 15 units. FG is 6 units long.
This means that the probability of p being on FG would be
which can be simplified to 
A rational expression is a ratio of two polynomials. To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same.
Answer:
since your adding to hours each time youll have 11, then the answer would be d the last one :)
Step-by-step explanation:
Square root of 12 (

)
Square root of 18 (

)
You can multiply these two together to get:

Therefore your answer is 6 square root of 6.
