Iam sorry i cant see the qusetion
A square since all sides are equal and the angles aren't acute so it can't be a rhombus
2(4x+5)>7x+20 perform indicated multiplication on left side
8x+10>7x+20 subtract 7x from both sides
x+10>20 subtract 10 from both sides
x>10
or in interval notation, x=(10, +oo)
So here. I don't know how to explain so-
You were using it for 6 hours because 70-25 is 45 and if you divide 7.50 and hour and 45 it’s 6
