Answer:
B. E(s) = s^3 - 29.
Step-by-step explanation:
The amount of empty space 
inside the cubic box is equal to the volume of the box minus the volume of the softball.
If the side length of the cubic box is 
, and the volume of the softball is 
, then the amount of empty space inside is
,
where 
is the volume of the cubic box.
Since it matches the equation we got above, choice B stands correct.
Theyre both divisible by 3
15n-18= 3(5n - 6)
keep in mind, that "t" is the time when the train at A station, left towards B station
they met, at some time "t", and by the time that happened, train from A
which started 3 hours earlier, had already covered "d" distance,
whatever that is
and the train coming from B, covered, 600-d, or the difference
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
Ed = 96 but switch the numbers
