Answer: z = 3
Step-by-step explanation: To solve this equation for <em>z</em>, we can first combine our like terms on the left side of the equation. Since 12 and 7 both have <em>z</em> after their coefficient, we can subtract 12z - 7z to get 5z.
Now we have 5z - 2 = 13.
To solve from here, we add 2 to the left side of the equation in order to isolate 5z. If we add 2 to the left side, we must also add 2 to the right side. On the left side, the -2 and +2 cancel out. On the right, 13 + 2 simplifies to 15.
Now we have 5z = 15.
Solving from here, we divide both sides of the equation by 5 to get <em>z</em> alone. On the left side, the 5's cancel out and we are simply left with <em>z</em>. On the right side, 15 divided by 5 simplifies to 3 so we have z = 3.

Answer:
The ends of the field are at the zeros (x-intercept) of the function.
0 = -0.000234(x - 80)2 + 1.5 subtract 1.5 from both sides
-1.5 = -0.000234(x - 80)2 divide both sides by right coefficient
6410.25641 = (x - 80)2 take square root of both sides
80.064 = x - 80 add 8-0 to both sides
160.064 = x
The field is 160.064 feet wide.
The maximum is at the vertex, y = 1.5 feet
