So we multiply 2 by 12, and get 24.

Then we multiply 8 by 3, and get 24.

Next we give both terms new denominators -- 3 × 12 = 36.

So now our fractions look like this:

<span><span>24/36</span>−<span>24/36</span></span><span><span>Since our denominators match, we can subtract the numerators.24 − 24 = 0So the answer is:<span>0/36 z</span></span><span>ero divided by anything is just zero. So that's the final answer:
<span>0</span></span></span>

2/3 - 8/12 =
First you change the both denominators to 12 by multiplying the 3 by 4 and the 2 by 4 so
2/3 : 8/12
8/12: 8/12
So your answer to 2/3 - 8/12 = 0

Factor completely 4x5 − 20x4 − 36x3. (1 point)
balandron [24]

Answer:

The factored form of given polynomial is x^3(4x^2-5x-9)

Step-by-step explanation:

Given the polynomial 4x^5 - 20x^4 - 36x^3

We have to factor the above polynomial completely.

4x^5 - 20x^4 - 36x^3

Take x^3 common from each term.

x^3(4x^2-5x-9)

Here, the quadratic polynomial is prime i.e it cannot be factored into lower degree polynomial. It has complex roots.

Hence, the factored form of given polynomial is x^3(4x^2-5x-9)

Please help: (picture)
Slav-nsk [51]

We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:


\frac{S}{356} = \sqrt{d}


Square both sides to get rid of the square root:


\frac{S^2}{126736} = d


Now plug the known value of the speed to find the distance:


d = \frac{140^2}{126736} = \frac{19600}{126736} \approx 0.15465


So the closest answer is the last one: d=0.155km

I need help thank you
Andreyy89

Answer: A

Step-by-step explanation:

For this problem, we need to understand how translations work.

As you can see, the triangles only slide to the right side, along the x axis. Therefore, we can eliminate B and C.

Now, we can see that the triangle has shifted by +8 units. Therefore, A is the correct answer.

Solve for h in this right triangle. Show all steps and round your answer to the nearest hundredth.
Elenna [48]

Answer:

708.56 ft

Step-by-step explanation:

Use the tangent trig rule, TOA in SOH-CAH-TOA. Take your opposite, h, and divide it over your adjacent, 875. Then take the tangent of 39° using a calculator, and multiply 875 on both sides to get h by itself, that being the result of 708.56 ft rounded.
