The algebraic expressions, and
are equivalent to
To determine whether each expression is equivalent to , apply the knowledge of algebra to solve each of the following in it's simplest form.
First, simplify as follows:
Add like terms
Next, compare or simplify where necessary each of the given algebraic expressions with
<em><u>First Option</u></em>
Add like terms together
Therefore, is equivalent to
- <em><u>Check the box for </u></em><em><u>YES.</u></em>
<u><em>Second Option:</em></u>
<u><em /></u><em> (cannot be simplified further)</em>
<em /><em />
Therefore:
- <em><u>Leave the box BLANK for </u></em><em><u>NO.</u></em>
<em><u /></em>
<em><u>Third Option:</u></em>
<em><u /></em><em><u> </u></em><em>(cannot be simplified further)</em>
<em /><em />
Therefore:
- <em><u>Leave the box BLANK for </u></em><em><u>NO.</u></em>
<em><u /></em>
<u><em>Fourth Option:</em></u>
<u><em /></u><u><em /></u>
<u><em /></u><u><em /></u>
Therefore:
- <em><u>Check the box for </u></em><em><u>YES.</u></em>
<em><u></u></em>
Thus, the algebraic expressions that are equivalent to are:
