Check out the attached images Figure 1 through Figure 4
Figure 1 corresponds to answer choice A
Figure 2 corresponds to B
and so on...
As you can see, we have
* Choice A's angles are corresponding angles BUT they are NOT congruent (due to the fact that BH and CG aren't parallel)
* Choice B has corresponding angles that are congruent due to the parallel lines given. These angles are on the bottom of each parallel train track and they are on the same side of the transversal. This is why they are corresponding angles. In other words, they are in the same corresponding bottom right corner of each four-corner angle configuration.
* Choice C has alternate exterior angles. The angles are on the outside of the parallel train tracks, and they are on opposite sides of the transversal.
* Choice D has alternate interior angles. They are on the inside of the parallel train tracks, and they are on opposite sides of the transversal.
So the answer is actually choice B
You would distribute the 3a to the other terms inside the parenthesis:
3a*8a=24a^2
3a*(-6b)=-18ab
Your answer would be 24a^2-18ab
Answer:
a. Simply shade in the bar diagram until it is roughly at 21%.
b. 
Step-by-step explanation:
See the attached image.
choice a is the correct answer
Answer:
7 cm
Step-by-step explanation:
base area = (base length x base height)/2 = (2x6)/2 = 6 cm^2
height = V / base area = 42 / 6 = 7 cm
