Answer:A
Step-by-step explanation:I’m pretty sure that the answer is rotation because it is clear that the triangle rotated over the graph.
#4 is 47, 48, 49
47+48+49=144
4
let the number be x
so by the question , 2x+5=13
solving this we get ,
2x=13-5
2x=8
so x=4
The answer would be 90 line ups
This is because 18 x 5 = 90
