for volume of prism you do area of cross section * height
area = 36
height = 15
=36*15
=540cm ^3
Answer: x=-7/2 y=29/2
Steps:
Use the elimination method
Multiply -3x+y=4 by 5 to make the coefficient next to the y in both equations the same
5(-3x+y=4)
-15x+5y=20
Then, subtract to eliminate the y
-15x+5y=20
- -9x+5y=-1
= -6x=21
Divide both sides by -6 to isolate x
= x= -7/2
Next substitute -7/2 into x in one of the equations
-3(-7/2)+y=4
-21/2+y=4
Add 21/2 from both sides to isolate y
y=29/2
For the same reason that a man is always a person but a person
is not always a man.
And the same reason that a 5th grader is always a student but a student
is not always a 5th grader.
A square is a special kind of rectangle ... one with all equal sides. If all the
sides are not equal, then it's still a rectangle, but it's no longer the 'special'
kind of rectangle.
