AAS Postulate
It is given that CE = BD so we know "S" (representing side) has to be in the three letter postulate.
It is also given that angle DBA and angle CEA are right angles, so therefore they are congruent. Now we know that an "A" must also be in the postulate.
Lastly, we know that the triangles have a second angle, EAB, in common because they share it overlappingly. So there must be another "A" in the postulate.
Now we need to look at the order in which it is presented. The order follows Angle, Angle, Side so the postulate must be the AAS postulate. Hope this helps!

Answer:
Lower bound = 5.2
Upper bound = 5.4
Step-by-step explanation:
If a= 4.2 to (1dp):
Upper bound = 4.2 + 0.05 = 4.25
Lower bound = 4.2 - 0.05 = 4.15
If b = 18 (to the nearest whole number)
Upper bound = 18 + 0.5 = 18.5
Lower bound = 18 - 0.5 = 17.5
Therefore:
Lower bound of ((a+b)/a) = ((4.15 + 17.5) / 4.15) = 5.2 to 1 decimal place
Upper bound of ((a+b)/a) = ((4.25 + 18.5) / 4.25) = 5.4 to 1 decimal place
The upper and lower bound are calculated to one decimal place.
3. Binomial Formula: ( a + b ) ( a - b ) = a^2 - ab + ba - b^2 = a^2 - b^2
4x^2 - 25 = (2x - 5)(2x + 5)
Answer: 13 comic books
Step-by-step explanation:
1st add 18 + 8 which equals 26
2nd subtract 130 - 26 which equals 104
3rd divide 104 / 8 because each comic book was $8
4th your answer is 13 comic books
