Hi help me with this please!!

The total number of photos on hannah’s camera is a linear function of how long she was in rome. she already had 44 photos on her camera when she arrived. then she took 24 photos each day for 6 days. what is the rate of change of the linear function that represents this

What is the remainder when 3x^2-x-10 is divided by x-1 -6,-7,-8, or -9

Marking brainliest for original answer.. are these two triangles similar? how can you tell?
