Answer:
Product of two expression is 
Step-by-step explanation:
Given : Expression -
and 
To find : The product of given expression
Solution : To find the product we apply distributive law

We write in the form of product and multiply term by term


Apply distributive law,



Therefore, Product of two expression is 
C is correct because absolute value cant be negative.
5x - 3 = 11 + 12x
---Subtract 5x from both sides
-3 = 11 + 7x
---Subtract 11 from both sides
-14 = 7x
---Divide both sides by 7 to leave x by itself
x = -2
Answer: x = -2
Answer Choice: A, -2
Hope this helps!
