First one should be correct. Counter clockwise goes around left. 90 degrees would go in a full quadrant.

Are you trying to solve for x and y?

y=2x+1; x+2y=17
sub in one variable in the other equation.
x+2(2x+1)=17
x+4x+2=17
5x=15
x=3

now that you have x value, plug into the original equation to find y and check with the other. 
y=2(3)+1 = 7
x+2y=17 = 3 + 2(7) = 17 ; 17=17

Answer:

B. 3 square feet

Step-by-step explanation:

The formula for surface area is:

2lw+2lh+2wh

Box F's surface area is just plugging in those variables

2(3)(3)+2(3)(3)+2(3)(3)=54

Box J's surface area is the same way

2(2)(4.5)+2(2)(3)+2(4.5)(3)=57

The difference is 57-54=3

The answer is B. 3 square ft
