Answer:
as illustrated
Step-by-step explanation:
X-4y= - 18
find 2 points on the line
x = 0 y = 4.5 (0, 4.5)
x = 4 y = 5.5 (4, 5.5)
Answer is
( x + 6) × ( x-7)
In order for the sum to be a positive integer, the sign of the other integer needs to be positive and the value needs to be greater than -5. If it wasn't greater than -5 or if it was negative then the sum of them would be a negative integer.

<em><u>Complete Question:</u></em>
The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?
<em><u>Answer:</u></em>
The numerator of fraction is -360
<em><u>Solution:</u></em>
Given that,
<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>
We have to solve the equation for "n"
Rearrange the equation
Thus the numerator of the fraction is -360
