To add the variables, add the coefficients with same variable. The expression which is equivalent to given expression is 
. The option 2 is the correct option.
<h3>What is
equivalent expression?</h3>
Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The expression given in the problem is,
Let the resultant expression of the above expression is 
. thus,
To add the algebraic terms open the brackets first,
Separate the same variable terms,
To add the variables, add the coefficients with same variable. Thus,
Hence, the expression which is equivalent to given expression is . The option 2 is the correct option.

All of the above are true
Answer:
Angles in ascending order:
Q, R, S
Step-by-step explanation:
The side with the biggest number also has the biggest angle degree. The side with the smallest number also has the smallest angle degree.
Answer:
Arithmetic
Step-by-step explanation:
An arithmetic progression is characterised by the first term (a), number of terms (n) and common difference (d).
3x + 6 = 27
step 1. subtract 6 from both sides
3x = 21
step 2. divide both sides by three to get x alone
x = 7
