Answer:

5(x + 3)(x - 3)

Step-by-step explanation:

Both terms in this expression have 5 in common---they both have a factor of 5. Therefore you can factor out a 5 like this:

5(x^2 - 9)

This can be even further factored. Find what two numbers multiply to -9 but add to 0. -3 and 3 are numbers that work. You can make x^2 - 9 become(x + 3) and (x - 3).

5(x + 3)(x - 3) is the final answer simplified completely.

In New York, state sales tax rates vary by county. In Allegany County, the sales tax rate is 8 1 2 %. a. A book costs $12.99, an
ArbitrLikvidat [17]

Answer:

$ 2.30

Step-by-step explanation:

Given that the sales tax rate = 8\frac{1}{2}\%=8.5\%

The cost of the book is $ 12.99.

So, the tax on the book= 8.5% of 12.99

= \frac {8.5}{100}\times 12.99

=1.10

So, the sales tax on the book is $ 1.10.

The cost of the video game is $ 39.99.

So, the tax on the book= 8.5% of 39.99

= \frac {8.5}{100}\times 39.99

=3.30

So, the sales tax on the book is $ 3.40.

The difference of taxes on both the items = $ 3.40-$ 1.10=$ 2.30

So, the tax on the video game is $ 2.30 more than then tax on the book.

MArishka [77]

Answer:

x = ±2sqrt(15)

Step-by-step explanation:

x^2 = 60

Take the square root of each side

sqrt(x^2) = ±sqrt(60)

x = ±sqrt(60)

x = ±sqrt(4 *15)

x = ±2sqrt(15)
