Answer:
SSS --> SAS --> AAS --> SAS --> HL --> SSS --> ASA --> AAS --> HL --> SAS --> HL
Step-by-step explanation:
To do this problem, look at the angles that are marked congruent as well as the sides. Then look at the order that the angles and sides are placed. If it is SSS, then that means three sides are marked congruent. SAS means the order of the side and angles would be side then angles then another side. AAS means angle then angle then side. HL is when you have a right triangle and one of the legs are congruent as well as the hypotenuse. ASA means an angle then side then another angle.
So recall that a difference of squares looks something like this:
= (x+2)(x-2)
Everything within the parentheses is the exact same-except for the plus and minus signs! If you multiply the first two terms (the two x's in the example above), you'll get
. If you multiply -2 by x and +2 by x, you'll get -2x + 2x, which equals 0 and cancel out. Then you multiply +2 by -2 to get -4.
So in the above options, only 16-81 is a difference of squares, since it simplifies down to (4x + 9)(4x - 9).
