The answer would be 12. To find this u would have to first add 8,12, and 15=36 Next, divide 36 by 3 =12
Consider the form x^2+bx+c. Find a pair of integers whose product is c and whose sum is b. In this case, whose product is 36 and whose sum is 20.
2, 18
Write the factored form using these integers.
(x+2)(x+18)
Though you did not list the points, I can tell you how to solve for the question.
One way to tell if a point lies on a given line is to take the point and plug it into the equation. If the equation remains true, then the point lies on the line. For example:
If we have the point (1,1), we can plug in 1 for x and 1 for y and see if the equation is true:
The answer to the problem is 2300
