yes. one input results in one output.
yes. one output results in one input.
no. at least one outpot results in two inputs.
no. at least one input results in two outputs.

step-by-stp

the correct answer is the section c

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.  

they share a side

step-by-step explanation:

this is the fundamental definition of adjacent angles

they:

1) share a vertex

2) share a side.
