Answer:
is equivalent to
and ![5.9x+(-2.6x)](https://tex.z-dn.net/?f=5.9x%2B%28-2.6x%29)
is equivalent to
and
.
The expressions which are equivalent to neither:
and ![5.9x-(-2.6x)](https://tex.z-dn.net/?f=5.9x-%28-2.6x%29)
Step-by-step explanation:
Given the expressions:
1) ![-2.6x-(-5.9x)](https://tex.z-dn.net/?f=-2.6x-%28-5.9x%29)
2) ![-2.6x+(-5.9x)](https://tex.z-dn.net/?f=-2.6x%2B%28-5.9x%29)
To find:
The expressions equivalent to the given expressions.
or the expressions which are not equivalent to any of the given expressions.
Solution:
First of all, let us solve the brackets from the given expressions.
can be written as
(because when we multiply a negative sign with negative, it becomes positive.)
Similarly
can be written as
(because when we multiply a positive sign with negative, it becomes negative.)
Therefore, the answer is:
is equivalent to
and ![5.9x+(-2.6x)](https://tex.z-dn.net/?f=5.9x%2B%28-2.6x%29)
is equivalent to
and
.
The expressions which are equivalent to neither:
