Call the integers 'N' and N+1.. Their sum is 2N+1. Twice their sum is 4N+2. . . Two more than that is 4N+4 and the question says that their product is equal to that. . So write N (N+1) = 4N +4, and then solve that equation to find N. I can tell you right now, by looking at it, that N is 4. You should solve the equation.
Step-by-step explanation:
Circumference =

Area =

Using r = 8 cm and

Circumference = 50.24 cm
Area = 200.96 sq cm
The answer is b) because if a number is to the left of a point on a line, it is less than the value of the point. If n=5, m must be less than 5
