Answer:
Step-by-step explanation:
The midline is half the length of the parallel base.
2(2x +36) = 3x +57
4x +72 = 3x +57 . . . . . . eliminate parentheses
x = -15 . . . . . . . . . . subtract 72+3x from both sides
Then the length of GH is ...
GH = 2x +36 = 2(-15) +36 = -30 +36
GH = 6
_____
The calculation steps are shown above. The strategy is to take advantage of the relation between the lengths of a midline and the corresponding base segment.
Answer:
The answer is A. If two polygons are congruent, then they are similar
Step-by-step explanation:
Just took the test!
The question is biased towards a response of preferring to use weight-lifting machines because it uses the words "hard" to describe free weights and "easy" to describe the machines, and may persuade some people to choose the machine.
The sample is not biased because it doesn't choose specific women, it includes all women who visit the gym.
