Printer A prints for 10 minutes, so prints
... (30 pages/minute)×(10 minutes) = 300 pages
Printer B prints for 7 minutes, so prints
... (40 pages/minute)×(7 minutes) = 280 pages
At the end of 10 minutes, the two printers will have printed
... 300 pages + 280 pages = 580 pages

Right- side expression:
Write the equation:
<span>3x^2 - 4 = 7x is the standard form. To get standard form into quadratic you must have one side of the equation equal zero. The easiest way to so is subtracting 7x on both sides of the equation.
</span><span>3x^2 - 4 = 7x
-7x -7x
3x^2 -7x - 4 = 0
So, </span>3x^2 -7x - 4 = 0 is the quadratic form.
