you'll first need to understand the symbols, I've attched a cheat sheet :)
you'll need to see if AB is linked to CD reversed.
If not then it's not A
For B you'll have to see if the angles are parralel to each other.
and for C you'll have to see if the angles are the same.
and D is the same as C
so the answer is ab=cd

You burn 265 calories running and then 7 calories per minute swimming.
Your friend burns 273 calories running and then 11 calories per minute swimming.
Let us assume that both of you swim for x minutes.
Calories burnt by you = 265+7x
Calories burnt by your friend = 273+11x
Difference between both = 273+11x-(265+7x)
= 273+11x-265-7x
= 8+4x
