we are given
we can also write it as
now, we can use factor formula
we can use above formula
we get
now, we can simplify it
now, we can set it to 0
and then we can solve for x
now, we can use quadratic formula
now, we can plug values
and we get
So, we will get solution as

It's 5 to 8. Adding red marbles in the problem is just to confuse you
Volume=length times width times height
it is possible for us to have a shorter length but have greater volume if the other 2 dimentions (width and height) are sufficiently great to compensate
example
box a is length 2, width 10 and height 20, volume is 400 cubic units
box b is length 3, width 4, and height 5, volume is 60 cubic units
the width and heigth must be greater
Answer:
isosceles obtuse triangle
Step-by-step explanation:
The attached graph shows a plot of the three lines.
The triangle is an isosceles obtuse triangle in the 2nd quadrant.
_____
It is convenient to let a graphing calculator plot these lines. If you're going to plot them by hand, it usually works best to choose values of the variables for the variable that has the largest coefficient (3 in two of the equations). That way, you're not trying to plot coordinates that contain fractions.
