Answer:

Step-by-step explanation:
We were given that:
and 
When x=5


When x=6


This implies that:

I teach you students to factor each term
26n^5 = 2 x 13 x n x n x n x n x n
12n^3. = 2 x 3 x n x n x n
For number one, i believe it would be 6x + 15Y-12. You just multiply 3 by everything i. the parentheses. I hope this helps :)
2x + y = 3 is the blue boundary line...the shading is below the line which means 2x + y is less than or equal to 3
y - x = 2 is the red boundary line... the shading is above the line which means
y - x is greater than or equal to 2
ANSWER: 2x + y is less than or equal to 3 and y - x is greater than or equal to 2
