Answer:

As can be clearly seen from the attached diagram angles PBC and BAD are congruent by the Corresponding Angles Theorem AB acts as the transversal for the lines BC and AD which are parallel.


Also, it can be clearly seen that the angles ABC and BAT are congruent by the Alternate Interior Angles Theorem as AB acts as the transversal for the lines BC and TAD which are parallel.


Thus, the only option from the given list of options which matches the answer is Option A.


Thus, Option A is the correct option and thus the final answer.

If UW = 9x – 9, what is UW in units?
Tju [1.3M]
I will answer this question to the best of my ability, because you have not provided a value of x to plug in.


UW is always equal to 9x-9 or 9(x-1) whenever x is a real number.  By plugging in x, we can get the value.  For example, if x was 4, we plug in x, giving us 9*4-9=36-9=27 units or 9(4-1)=9(3)=27 units
Don't forget to include units when you complete your answer!

Hope this helps!  I did as much as I could!

If (x - 2) is a factor of 2x³ + x² - 3 then for the value of x = 2 the polynominal is equal zero.
Substitute:
2 · 2³ + 2² - 3 = 2 · 8 + 4 - 3 = 16 + 4 - 3 = 17 ≠ 0
Answer: B) (x - 2) is not a factor.
