2 answers:
Answer: a)
b) Your Friend
Step-by-step explanation:
Given : After a week of rain, tadpoles appeared in your pond. After t minutes, you have (i) tadpoles and your friend has
(ii)tadpoles.
a) Now, the expression that represents the number of tadpoles you and your friend caught together will be :-
Hence, the required expression :
b) At t=9 , number of tadpoles you have = (using (i))
Number of tadpoles you have = (using (ii))
Since , 69> 68
It means your friend has more tadpoles after 9 minutes.

Step-by-step explanation:
Given
According to the order of the vertices,
- side AB in triangle ABC (the first and the second vertices) is congruent to side AD in triangle ADC (the first and the second vertices);
- side BC in triangle ABC (the second and the third vertices) is congruent to side DC in triangle ADC (the second and the third vertices);
- side AC in triangle ABC (the first and the third vertices) is congruent to side AC in triangle ADC (the first and the third vertices);
- angle BAC in triangle ABC is congruent to angle DAC in triangle ADC (the first vertex in each triangle is in the middle when naming the angles);
- angle ABC in triangle ABC is congruent to angle ADC in triangle ADC (the second vertex in each triangle is in the middle when naming the angles);
- angle BCA in triangle ABC is congruent to angle DCA in triangle ADC (the third vertex in each triangle is in the middle when naming the angles);
