Step-by-step explanation:

Both equations use x squared

Answer:

The common facor is x-3.

Step-by-step explanation:

The first expression can be factored with a difference of squares, x+3 and x-3. You can check that by multiplying them together to get x²-9. Knowing that you need a common factor, one that works for both expressions, you can immediately eliminate A and B. The second expression, x²-5x+6, has to share one of these two factors. To factor this, you find the numbers that multiply to the c term and add to the b term. (Ax²+bx+c) so b is -5 and c is 6. All you have to do is find out which two numbers add to -5 and multiply to 6. You start with factors of 6, which are +-6 and +-1, and +-3 and +-2. Say you try 6 and 1 first. The b term is negative, so these two added have to add to a negative number, which means positive 6 and positive 1 won´t work. The only way to add to -5 is to add 1 to -6 or -6 to 1, but multiplying those together gives you -6, and you need positive 6 in the c term. That leaves you with -2 and -3. they add to -5, and multiply to -6, which means that your common term is x-3. Test this by expanding your result, (x-2)(x-3), if you get the original expression theyre both factors.

If you walk 3 kilometers in 30 minutes, what is your average speed in kilometers per hour?

Answers

Answer:

If you walk 3 kilometers in 30 minutes your average speed is 6 kilometers per hour.

Therefore, the avearge speed in kilometers per hour is [tex]0.1[/tex] kilometer per hour.

What is the speed?

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Here given that,

Here, you walk [tex]3[/tex] kilometers in [tex]30[/tex] minutes. So the average speed is :-

Speed = Distance/ Time

Distance is [tex]3km[/tex] and the time is [tex]30[/tex] minutes so,

[tex]S=\frac{3}{30}\\\\\\S=0.1[/tex]

Hence, the avearge speed in kilometers per hour is [tex]0.1[/tex] kilometer per hour.

Mikey solved the inequality problem below incorrectly. Explain her error and redo the problem showing the correct answer.
Original problem: -4x+8<32
Mikey’s math work: -4x+8-8<32-8
-4x÷-4<24÷-4
x<-6

Answers

Answer:

Question 1: add 3a + 4a becuase they have the same variables. you should get 7a. Then subtract 10b and 4b because they have the same variables,You should get 6b. The answer is 7a+6b because you can't do anything with those numbers because of their variables and how they are not the same.

Question 2: The answer is x=10. to get the answer move all terms not containing x to the right side of the equation and add as normal.

Question 3: The answer is -5. Steps: move the equation around so there is a 2 on both sides of the equation, should look like this: 2x= -12 +2. Then add -12 +2 = -10. Then divide each term by 2 and simplify, should look like this: 2x/2 = -10/2. Then cancel the comments factor which is 2 should look like this: x = -10/2. After divide x by 1. Then divide -10 by 2 which equals -5.

Question 4: The answer is m=6. First multiply 6x2=12 then multiply that by 2 which should get u 24 then divide 24 by 4 =6

Question 5: sry I dont understand :(

Answer:

1. 7a+6b because 3a+4a=7a and 10b-4b=6b

2. x=10 because you add 3 to the other side to cancel it out and 7+3=10

3. x=6 because

2*m=2m and 2*6=12

24-12=12 and 12/2=6

Thanks1. What is the function of a top predator in an ecosystem?A. It increases the food for other predator species. B. It creates imbalance in the ecosystem.C. It maintains populations. **D. It helps increase the number of prey.Reason - The answer is C because predators couldn't possibly increase the food for other predators. They obviously don't imbalance the ecosystem since they help keep it cycling. And they can't increase the number of prey if they're eating prey so therfore you're left with C.2. Which is considered a top predator in the ocean? A. A shark**B. A sea lionC. A small whaleD. A bird.Reason - The answer is A because actually the top predator in the ocean is the killer whale but since it's not an option, you'd wanna go for a shark. A small whale obviously couldn't eat a big shark, nor could any of the others. :)3. What happens to an ecosystem during normal seasonal flooding?A. The biodiversity of the area reaches equilibrium.B.

How is the impact of seasonal flooding different from damming a river? A. Seasonal flooding helps balance biodiversity, but damming does not. B. Seasonal flooding is not considered an ecological disturbance like damming.C. Seasonal flooding does not impact biodiversity for as long term as damming.**D. Seasonal flooding increases biodiversity, but damming does not.Reason - Again, trying to finish this and tired of typing reasons but the answer is indeed C because damming a river can causes long-term damage to biodiversity and the ecosystem while it can quickly recover from a flood because it doesn't really damage as much and the flood will simply be gone after a bit. :)5. Would a long-term increase in the average temperature of a region be considered a significant disturbance in the ecosystem?A. No, because it would not create large-scale changes in the environment. B. No, because increases and decreases in average temperatures are normal.C. Yes, because such a change could have a large-scale impact on wildlife. **D. Yes, because any slight change in temperature is considered a distribution.Reason - Eh.. it's pretty self explanatory.
