Answer:
C
Step-by-step explanation:
y is greater or equal to 0
x is also greater or equal to 0
you can see that only one answer choice can be the answer
the line is x-y = 2
the upper side is x-y <= 2
proves that c is the answer
Answer:
the perimeter of the rectangle = 2(length + width)
= 2(4x^2 + 2 feet + 5x^2 + 3x feet )
= 2(4x^2 + 5x^2 + 2+ 3x)feet
= 2(x^2(4+5) + 2+ 3x) feet
= 2(9x^2 + 3x + 2)feet
= 18x^2 + 6x +4 feet
