Answer:

Step-by-step explanation:

The "key" to this is to recognize that the two lines have to be the same length, they put the drawing on it's side to make it harder to see that. :/  But another way to see this is that it's an isosceles triangle and you know the two legs that they are asking us about have to be the same length,  knowing that.. we can set the two expression equal to each other

3x - 10 = 2x

now solve for x

3x - 10 -2x = 2x - 2x  ( subtracting 2x from both sides )

3x - 2x - 10 = 0

x - 10 = 0

x - 10 + 10 = 0 + 10

x = 10    ( yay)

-89442719.1

Step-by-step explanation:

-12 × 5.47722558 =-657267069

3×2.44948974 = 7.34846923

657267069/7.34846923= -89442719.1

the square root of 30 is 5.47722558 which is multiplied by 12 to make -657267069

you the find the square root of 6 which is 2.44948974 and multiply it with 3.

after all, you divide -657267069 by 2.44948974 which is -89442719.1

what is the value of x in simplest radical form?

Answers

Answer:

25

Step-by-step explanation:

For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.

Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.

NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!

With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.

This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.

This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.

And that, my friend, is your answer. Hope this helped :)
