Expand.<br> If necessary, combine like terms.<br> (3+4.)(3 - 4x) =
gogolik [260]

Answer:

-16x^2 +9

Step-by-step explanation:

To start this problem I would rearrange so that the terms with the x's come first. Making it look like this

(4x+3)(-4x+3)

Now you take the 4x and distribute it to the -4x and the 3.  

-16x^2+12x  This is the first part

Take the 3 and distribute it to the -4x and the 3 as well.

-12x+9

All you do now is combine the twoso you'd have

-16x^2 +12x -12x +9  Notice there are two terms that have a regular x with no exponent. This means you can combine them to simplify further.

-12x+12x=0  So you no longer have to include this term in your answer.

-16x^2+9 Would then be your final answer.

After the advance-purchase deadline passes, the cost of attending a particular event is $99, which is 10% more than before. What
Harman [31]

The advance purchase price is $90.

Step-by-step explanation:

Ticket price after deadline = $99

Let,

x represents the advance-purchase price.

Suppose that the advance purchase price is 100%.

As 10% increases, the amount becomes;

(100+10)% = 110%

The amount after deadline is 110% of advance purchase price.

110% of x = 99

\frac{110}{100}*x=99\\1.1x=99

Dividing both sides by 1.1

\frac{1.1x}{1.1}=\frac{99}{1.1}\\x=90

The advance purchase price is $90.
