Explaining step by step the simplest form of the expression 9r(r+3)-2r(r-4)

Mathematics

Lynna [10]3 years ago

For simplest form, the first thing you'll want to do is get rid of the parentheses:

<span>9r(r + 3) - 2r(r - 4) = 9r^2 + 27r - 2r^2 + 8r 

Now we want to combine like terms:

</span><span>9r^2 + 27r - 2r^2 + 8r = 7r^2 + 35r</span>

An item is regularly priced at $60 . Jessica bought it on sale for 65% off the regular price. How much did Jessica pay?
adoni [48]

First, convert the 65% to a real mathematical number. For percents, this is always done by dividing the 65% by 100%, or 65% / 100% = 0.650.

Second, find out what 65% of $60 is. This is the amount of the sale discount. This is always found by mulitplying 0.650 by the item's cost $60, like this:

0.650 x $60 = $39.00.

So for this sale, you'll save $39.00 on this item.

This means, the cost of the item to you is

<span>$60 - $39.00 = $21.00.</span>
