Answer:
x = 8
y = 6
Step-by-step explanation:
First and foremost, it's an equilateral triangle, therefore all sides and angles are equal.
Knowing that the sum of angle in a triangle is 180°, therefore each angle is 60°.
Then equating (7x+4)° to 60, we have that,
7x+4=60
7x=60-4
7x=56
x=56÷7
x=8.

The expressions which are equivalent to neither:
and 
Step-by-step explanation:
Given the expressions:
1)
2)
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
is equivalent to and .
The expressions which are equivalent to neither:
and
7(x+y) because their both factors of 7
