Dafna1 [17]

We need to find the maximum (Vertex of the function)

Let:

L = Length = 1500 - 2x

W = Width = x

The area is given by:

\begin{gathered} A=W\cdot L \\ A=x(1500-2x) \\ A=1500x-2x^2 \\ A(x)=1500x-2x^2 \end{gathered}

We can find the maximum using the following formula:

\begin{gathered} xm=-\frac{b}{2a} \\ where \\ a=-2 \\ b=1500 \\ so\colon \\ xm=-\frac{(1500)}{2(-2)}=\frac{1500}{4}=375 \end{gathered}

Evaluate the area for the value we found previously:

A(375)=-2(375)^2+1500(375)=-281250+562500=281250

The largest area that can be enclosed is 281250m²

snow_tiger [21]

Answer:

The caterer served 5 hours. x = 5

Step-by-step explanation:

25x + 225 = 350

We must use inverse operations to get x

25x + 225 - 225 = 350 - 225

25x = 125

25x ÷ 25 = 125 ÷ 25

x = 5

the caterer served 5 hours.

I hope this helped and if it did I would appreciate it if you marked me Brainliest. thank you and have a nice day!
