Answer:
2bc
Step-by-step explanation:
The product of c and b means c X b. However, in algebra, we typically miss out the X (multiply) symbol. We also like to put letters in alphabetical order. So this means the product of c and b is written as bc.
Then, to double a number, this just means to multiply by 2.
so we have 2Xbc. But, again, we don't write in the multiply symbol. We also put numbers in front of letters.
So this becomes 2bc.
