How to get B from A
It can be seen that B is a factor of A.
And to get B from A, all you need to do is divide both sides of A by 3.
i.e.
Hence, from the list of given options.
<em>Option C answers the question because 3 is a non zero constant and both sides of the equation were divided by 3</em>
Please see attached file for the triangle’s figure:
Going with the image attached, if DE is parallel to BC<span>
then
<span>4: (4 + 5) = 6 : (6 + 7).
Therefore, the inequality that she will use to contradict the assumption</span>
is 4:9 ≠ 6:13</span>.
To add, a relation that holds
between two values when they are different in mathematics is called an inequality. A is not equal to b also means the notation a ≠ b.
