Answer:
The one on the bottom CANNOT be represented by the equation.
Step-by-step explanation:
For the equation in the problem there has to be a 4x, meaning the cost per case multiplied times the about of them (x). Then there has to be a +7 somewhere in the equation for shipping. The two on the top fit both of those descriptions.

Answer:
the width is 470 ft and the length is 730 ft.
Step-by-step explanation:
Perimeter of a flag is 2l+2w
Let w = width
Let l = w+260
2(w+260)+2w=2,400
2w+520+2w=2400
4w+520=2400
4w=1880
w=470
So, the length would be 470+260, or 730
Therefore, the width is 470 ft and the length is 730 ft.
I hope this helped and have a good rest of your day!

Answer:
j=-2
Step-by-step explanation:
42j+18-19j=-28
Combine like terms
23j +18=-28
Subtract 18 from each side
23j +18-18 = -28 -18
23j =-46
Divide each side by 23
23j/23 = -46/23
j = -2
