Answer:
The diagonal is 421.
Step-by-step explanation:
This is a difficult question. To find the diagonal, you need to find the base and the height of the square. After that, you need to make it a triangle, by using this equation; 
(A being area, B being base, and H being height) then find the length of the hypotenuse of the triangle, which I will do for you.
The B and H = 416. Plug it into the equation now;
Now that you have done that, we know that the area of our new triangle is 86,528.
The diagonal is: 
If they pay $28 for 16 jerseys then the total they’d have to play is $448
28 x 16 = 448

1/3x + y = 4....subtract 1/3x from both sides
y = -1/3x + 4 <===
