Answer:
11 + x + 19*x
Step-by-step explanation:
The sum of eleven, a number, and the product of nineteen and the number.
we have to read carefully and understand how to interpret
when he says the sum of separates into 3 parts because there is a "comma" and an "and"
Now let's separate the 3 parts of the sum
1 part
says eleven so we just put 11
eleven = 11
2 part
in the text it says that we replace "a number" with x
a number = x
3 part
In this case we simply make the product between the given values
the product of nineteen and the number
19 * x
Now we can accommodate everything and we finish
11 + x + 19*x
