Answer:
11+x^2/3
Step-by-step explanation:
“Eleven more” means you add 11 somewhere in the expression.
11+
The “quotient” is the answer to a division problem, so “the quotient of a number squared and three” translates to the answer to a number squared divided by 3.
11+x^2/3
“A number” in the question would be x, because it’s the unknown value.
I hope this helps!
