Well, it depends what shape you are using the volume formula for. If it's for a square (I'm assuming) then the volume formula would be:
Side^2
C I think because it shows the months and the total
we have
----> inequality A
The solution of the inequality A is the interval ------> [-1,∞)
-------> inequality B
The solution of the inequality B is the interval ------> (-∞,7]
The solution of the compound inequality is
[-1,∞) ∩ (-∞,7]=[-1,7]
therefore
the answer in the attached figure
MP = 15 -3 = 12
h/MP = 3/h
h / 12 = 3/h
h^2 = 36
h = 6
angle a and angle e are obtuse angles
