Which of the following is not a characteristic of non-euclidean geometry?

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.

texaschic101 is correct for all of them expect for the last one (question 6) she needed to finish the problem by multiplying 360 by 80%

step-by-step explanation:

x=0.8x+72

x=0.8x-0.8x+72 (move like terms to the same side)

0.8x-x=72 (collect like terms)

0.8x-x=0.2x

0.2x=72 (divide both sides by 0.2)

x=360

now because it said 80% of members were 30-40 and wants to know how many members joined between the age of 30 and 40 we need to multiply 360 and 80%

360 x 80%= 288

x=288
