Answer:
20
Step-by-step explanation:
You need to add all four then divide the answer by 4.
Hope this helps.
Answer:
see below
Step-by-step explanation:
If suffices to look at the last term. It must simplify to 4/(3w²), so the exponents of z must match in numerator and denominator, and the ratio of constants must reduce to 4/3.
The exponents of z have the right values in choices B and D, but the ratio of constants only matches in choice D. Looking at the rest of choice D, we see that we can factor 6w²z² from both numerator and denominator, then factor 2 from the remaining numerator to make it match the desired form.

Answer:
i believe it is the answer on the right because alternate interior angles add up to 180 degrees
They are because they are even and the exact same
