Answer:

x = ±2√10

Step-by-step explanation:

(√40 - x)(√40 + x) = 0  

⇌

x = √40  or  x = -√40

we can go further and say that √40 = 2√10

Answer:

The number of sandwiches sold is 73. This is because it is multiplied by the expression for the money received per sandwich.

The cost to make each sandwich is <em>S. </em>This is stated in the first sentence of the problem.

<em />

The profit is 0.2<em>S. </em>This is because they sell each sandwich for an additional 20% of the cost ( S )

<em />

The amount of money the band receives is (<em>S </em>+ 0.2<em>S </em>). This is because it is the price per sandwich.
