A company wants to try out two new toothpaste brands (brand A and brand B) on customers who use the company's existing toothpaste brand.

So, the best method for this study is an experiment.

As the company will try its two new brands who are already using their existing toothpaste brand.

They will get to know their like and dislike about their two new toothpaste brands.

Hence, Second option is correct.

What's the answer? Can't figure it out
soldier1979 [14.2K]
9x⁹ - 90x⁸ - 351x⁷

What do each of these numbers have in common?

They ALL have 9x⁷ in them!

So, divide each one of these by 9x⁷

9x⁹ ÷ 9x⁷ = 9x²

-90x⁸ ÷ 9x⁷ = -9x

-351x⁷ ÷ 9x⁷ = -39

So, factorized completely, it is :

9x² - 9x - 39

~Hope I helped!~

A bicycle that usually sells for $230 is on sale for 25% off. What is the sale price?
zloy xaker [14]
The answer is $57.50.

Explanation:
To find the discounted price of an item, you multiply the original sell price of the item by a decimal version of the percentage. So in this case you would multiply .25 by 230 to get 57.5 or $57.50.

I hope I helped and good luck!

Coordinates (-3, 5), ( -3, 8), and (2, 5). The triangles was dilated by a scale favtor of 3. What is the area of the dilated tri
Otrada [13]

Answer:

The area of the triangle is 7.5 unit²

Step-by-step explanation:

Here we have the coordinates given as

(-3, 5) (-3, 8) and (2, 5)

Let us call the points A = (-3, 5)

B = (-3, 8) and

C = (2, 5)

Therefore the lengths of the sides of the triangle are

AB = a =  \sqrt{(-3-(-3))^2+(5-8)^2} =  3

AC = b = \sqrt{(-3-2)^2+(5-5)^2} =  5

BC = c = \sqrt{(-3-2)^2+(8-5)^2} =  \sqrt{34}

Therefore the Area can be derived from Heron's formula which is

A =  \sqrt{s\times (s-a)\times (s-b)\times (s-c)} where s = semi perimeter or (a + b + c)/2

Therefore, plugging the values, we get

s =   (3 + 5 + √34)/2 = 6.9155≈6.92

A =  \sqrt{6.92\times (6.92-3)\times (6.92-5)\times (6.92-\sqrt{34} )} = 7.499≈7.5.
