Answer:

A = (x^2)/2

Step-by-step explanation:

Represent the length of one side of the square by s.  Then, according to the Pythagorean Theorem,

x^2 = s^2 + s^2, or x^2 = 2s^2, or (solving for s^2), s^2 = (x^2)/2

This last result is the area of the square in terms of x:  A = (x^2)/2

The following equation: C=43x+14100gives the total cost, in dollars, to produce x units of a product at a factory. If the monthl
Masja [62]

We have

C is the cost

x is the units of a product at the factory

If

C= 35170

we need to find the value of x

The equation given is

C=43x+14100

so we have the value of C, so the equation if we substitute the value of C is

35170=43x+14100

we need to isolate the x

\begin{gathered} 35170-14100=43x \\ 21070=43x \\ x=\frac{21070}{43} \\ x=490 \end{gathered}

In that month,490 units can be produced for $35170.​
