Question

Write an expression that says "Nine plus a number times 14"

Answer 1

(9+n)x14 is the expression

Answer 2

That could be expressed in two different ways ... because
there are no parentheses in your question.

One way:
Call the number ' N ' .
Nine plus the number is (9 + N)
That much times 14 is 14(9 + N) .

The other way:
Call the number ' N '.
The number times 14 is 14N
Nine plus that is 9 + 14N .
