What is the product in simplest form x^2+9x+18/x+2 times x^2-3x-10/x^2+2x-24

german

$\dfrac{x^2+9x+18}{x+2}\cdot\dfrac{x^2-3x-10}{x^2+2x-24}=\dfrac{x^2+6x+3x+18}{x+2}\cdot\dfrac{x^2-5x+2x-10}{x^2+6x-4x-24}\\\\=\dfrac{x(x+6)+3(x+6)}{x+2}\cdot\dfrac{x(x-5)+2(x-5)}{x(x+6)-4(x+6)}$

$=\dfrac{(x+6)(x+3)}{x+2}\cdot\dfrac{(x-5)(x+2)}{(x+6)(x-4)}=\dfrac{(x+3)(x-5)}{x-4}\\\\=\dfrac{x^2-5x+3x-15}{x-4}=\dfrac{x^2-2x-15}{x-4}$

Answer:

4.9 units

Step-by-step explanation:

We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.

a being 4, and b being 3.

We need to use the Pythagorean Theorem to solve this.

$a^2 + b^2 = c^2$

we can rewrite this as;

$4^2 + 3^2 = c^2\\$

Calculation time

15 + 9 = c

c = 24

Now we find the square root of each equation to determine what $c^2$ is.

$\sqrt{15}+\sqrt{9}=\sqrt{24}$

4 + 3 = 4.89897948557

Let's round that to the nearest tenth.

4.9 units

Hope this helped :)

Select the equation that represents the question.

Pani-rosa [81]

Answer:

12=0.005×w
the number is 2400

Step-by-step explanation:

An appropriate representation of the problem can be had by using a variable to represent "what number" and then using the math equivalent symbols for the English words. If "what number" is represented by w, then we want to translate ...

0.5% of w is 12 . . . . English

0.005 × w = 12 . . . . . . . matches choice 1

This can be solved by multiplying by 200

200(0.005w) = 200(12)

w = 2400

The number is 2400.
