Okay so first you want to simplify the given equation (7x+3y)(7x-3y)
in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2
Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2
Its as easy as pie!
18/27 can be reduced to 2/3 so the second option should be the correct answer
Do $15,000x.014x2
--
$15,000x.014=$210
$210x2=$420
A 2 liter bottle would hold more.
What do you mean? Pls state the question correctly
