What is the system of equations shown in the graph?

The perimeter of a rhombus with a side of 6 is 24

The parabola x= √y-9 opens: a.)up b.)down c.)right d.)left

Offering 30 if a plus b plus c equals 68 and ab plus bc plus ca equals 1121, where a, b, and c are all prime numbers, find the value of abc. the answer is 1978 but i need an explanation on how to get that.
