1. 2\Xb2 2013 8x, 2. -3s\Xb2+9s, 3. 4x + 20x\Xb2, 4. 5t - 10+\Xb2, 5. S\Xb2 + 8s+ 12

1. 2² – 8x
2. -3s²+9s
3. 4x + 20x²
4. 5t - 10+²
5. s² + 8s+ 12

 

Answer:

1. 2^2-8x

4-8x=0

4=8x

8 8

×=4/8 or in simple terms 1/2

If yore looking only for the factors, 4(1-2x)

2. -3s^2+9s

-3s^2+9s=0

9s=3s^2

3s 3s

3=s or s=3

But if yore just looking for the factors of the equation, -3s(s-3)

3. 4x+20x^2

4x+20x^2=0

20x^2=-4x

20x 20x

x=-4/20 or -1/5

**If only for factors, 4x(1+5x)

4. 5t-10t^2 (If the plus sign is a typo and its just letter t)

5t-10t^2=0

5t=10t^2

10t 10t

5/10=t

t=5/10 or 1/2

**If only for factors, 5t(1-2t)

5. s^2+8s+12

(s+6)(s+2)

5x\Xb2-45y\Xb2 How To Solve

5x²-45y² how to solve   Answer: simplified it can be x²-9y² Step-by-step explanation: its simple just get the GCF or greatest common factor of every numerical coefficients in a term. That is 5 and -45. The GCF of 5 and -45 is 5. Divide it to every terms. That is 5x²/5 and -45y²/5 and the answer is x²-9y².

How To Compute The Distance Of The Epicenter From Each Of The Stations Using This Formula?, D=Td Over 8 Seconds Multiply 100 Km?

How to compute the distance of the epicenter from each of the stations using this formula? d=td over 8 seconds multiply 100 km?   Here are the steps in finding the distance from the seismic station to the earthquake epicenter. Get data from the seismic station with regards to the seismic waves. Identify the time difference in the arrival of p-wave and s-wave. Let say in  this example the time difference between the arrival of p and s- wave is 30 seconds . Base on the time difference (in seconds) in the arrival of p-wave and s-wave, we can use the formula                    distance = TD (time difference) / 8 seconds   ×  100 km             Solution:           distance = (30 s / 8 s) × 100 km    (cancel out unit second)                          =  3. 75   × 100 km                          =     375 km This data means that if the time difference in the arrival of p-wave and s-wave is 30 seconds, the distance of the seismic station to the earthquake epicenter is 375 km.
