The scale factor that was used in the dilation could be 1.5 units.
What is scale factor?Suppose a figure (pre image) is dilated (dilated image) by scale factor of k. So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as scale factor.
The quantities that are squares or multiple of linear things twice grow by square of scale factor.
So area of first figure = k² × area of second figure
Similarly,
The Volume of first figure = k³ × volume of second figure.
Since the scaling is done by product of some constant, that constant is called scale factor.
Then we have:
K = 4/6
K = 2/3
K = 1.5 units.
Thus, scale factor is the ratio of the new measurement to the old measurement therefore, the scale factor that was used in the dilation could be 1.5 units.

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.

A cake recipe requires flour and sugar in a ratio of 4 to 3. Which table has been generated using this ratio?
Answers
Answer:
The third table
Step-by-step explanation:
A ratio is a relationship that illustrates how many times one number contains another. For example, the ratio of 4:3 means there is 4 cups of flour for every 3 cups of sugar. The third table is the only one that increases proportionate to the ratio. This can be seen because when 4 is multiplied by 3 to get 12, so is 3 to get 9. This pattern continues, with both amounts being multiplied by the same number.

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.

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
