Final answer:
The expression 1+10x+6x can be simplified by combining the like terms to get 1 + 16x, which is the simplified expression.
Step-by-step explanation:
The expression given by the student, 1+10x+6x, needs to be simplified by combining like terms.
To simplify the expression, add the coefficients of the x terms.
The x terms are 10x and 6x, and when combined (10x + 6x), they equal 16x.
Therefore, the simplified expression is 1 + 16x.
To check if the answer is reasonable, reassess the addition of the coefficients.
The original terms 10x and 6x indeed add up to 16x, confirming the simplification is correct.
