Answer:
100 units squared
Step-by-step explanation:
The area of a square is A=s^2, where s is the side length. So, in your problem, the area would be A=(x+1)^2. If x = 9, then the formula would be A = (9+1)^2 = 100.
Answer:
10
Step-by-step explanation:
If x = 9 and the equation is x + 1 it would turn into 9 +1, and 9 + 1 = 10
