Question
For given expression, select one correct equivalent expression from the four options.18xy + 45x
- 18xy − 45x
- 9x (2y+5)
- 18yz + 45x
- 3x (6y+18)
Hint:
you can take common from all terms and write it outside the bracket and then match all options one by one .
The correct answer is: 9x (2y+5)
Step 1: As 9x (2y+5) = 18xy + 45x, the given expression
Step 2: Only option B is the correct equivalent expression
