Draw a number line with 10 positives and 10 negatives. Count from 0 to 8. Now, from 8, count back 12 spots. From that spot, go back to 0, which is their original position. The number you counted there is your answer.
As we know that the area of a rectangle is -
length × Breadth
So, here length = (3n+1)
Breadth = (2n-5)
Area of rectangle
= (3n+1)(2n-5)
= 3n(2n-5)+1(2n-5)
= 6n² - 15n + 2n - 5
= 6n² - 13n - 5
Answer) Area of rectangle is 6n² - 13n - 5
only integers and polynomials are under subtraction.
