I believe the answer is 81x^4-16x^2 difference of squares
Answer:
U can determine that lines e and f are not parallel
Step-by-step explanation:
By remembering vertical angles, u can find all the angles for the diagram. The top are: 110, 70, 70, 110. The bottom four are: 105, 75, 75, 105. As u can see they're not the same so the lines cannot be parallel
3/5 of the album is full....leaving 2/5 pages that are not full. 2/5(30) = 60/5 = 12 pgs not full (12 remaining pages)
she wants to set aside 1/4 of the remaining pages...
1/4 of 12 = 1/4(12) = 12/4 = 3 pgs set aside for vacation
12 - 3 = 9 pgs...she can fill 9 pgs before the vacation

Answer: SAS</h3>
=================================
How to get this answer:
We're told that AD = BC, so that is one pair of sides that are congruent. This forms the first "S" in "SAS"
The "A" refers to the congruent angles, which happen to be angle DAB and angle CBA, both are 90 degrees
The second "S" in "SAS" is the second pair of congruent sides. Those two sides are the overlapping shared side of AB. It might help to peel the two triangles apart to get a better look.
Note how the angles are between the two pairs of sides mentioned.
