Question
Which expression is equivalent to
Hint:
Hint:
- An expression is a combination of symbols used in algebra, containing one or more numbers, variables, and arithmetic operations
The correct answer is:
Explanation:
- We have given a expression
- We have to simplify the given expression and find the equivalent expression among the options.
- We will use basic mathematical operation like adding subtracting like terms and then simplfy it.
Step 1 of 1:
We have given equation
Firstly, we will open the brackets,
Ie,
Now we will take like terms together,
Ie,
On further simplification, we will get
So, Option (A) is correct.
Final answer:
Hence, The equvalent expression of 
.
So, Option (A) is correct.

Solve each inequality and graph the solution :
x-8.4≤2.3
Whenever we use the symbol ≤ or ≥ , we use the endpoint as well. So, we use complete line to graph the solution.
