Let 'a' represent the number of adult tickets.

a +(a -73) = 427

2a = 500 . . . . . add 73

a = 250 . . . . . . divide by 2

<em>Additional comment</em>

I call this a "sum and difference problem" because we are given the total of two values and the difference between them. As you can see here, the larger of the two values is the average of the given numbers, their sum divided by 2. This is the generic solution to such a problem: the larger number is the average of the given sum and difference.

F(x)=2x+6

mrs_skeptik [129]

Answer:

The Correct option is B. B.-10x^2-48x-54

Therefore the product of f and g. is

$F(x)\times G(x)=-10x^{2}-48x-54$

Step-by-step explanation:

Given:

F(x)=2x+6

G(x)=-5x-9

To Find:

The product of f and g.

F(x) × G(x) = ?

Solution:

The product of f and g.

$F(x)\times G(x)=(2x+6)(-5x-9)$

Applying Distributive Property we get

$F(x)\times G(x)=(2x(-5x-9)+6(-5x-9)\\=-10x^{2}-18x-30x-54\\$

Combining like terms we get

$F(x)\times G(x)=-10x^{2}-48x-54$

Therefore the product of f and g. is

$F(x)\times G(x)=-10x^{2}-48x-54$
