We know that 6x(-7) is -42 and we also know that 6+(-7) is -1.

So we can write

[tex]x^2+6x-7x-42[/tex]

[tex]x(x+6)-7(x+6)[/tex]

[tex](x-7)(x+6)[/tex]

So our solutions are [tex]x=7,-6[/tex]

Edgenuity’s sample response for this question:

Sublimation occurs because the atoms in a solid must gain enough energy to form a gass without passing through the liquid state. Low air pressure and large amounts of energy, often in the form of heat, allow the atoms to move fast enough to overcome the attractive forces between them.

If you need an original response here’s my take!!:

Sublimation happens when a solid turns directly into a gas. For this to happen, there must be low air pressure and immense heat energy. This allows atoms to quickly move and perform sublimation.

The radius of a circle is 4.8cm. What is the diameter?

Answers

Answer:

9.6cm

Step-by-step explanation:

Since the radius is half of the diameter, to find the diameter, simply multiply the radius by 2.

4.8*2=9.6

Diameter=9.6cm

Anyone know how to do this?? Help pls

Answers

Answer:

The correct answer is A. a = 2s - b - c

Step-by-step explanation:

First you multiply 2 on both sides and you will end up with 2s = a + b + c.

Then to isolate a you would subtract both b and c from both sides of the equation as well to end up with your answer of a = 2s - b - c.

#6 is 17 days

Step-by-step explanation:

This is how I answered it

1) 2750 = 550 + 125x

2) subtract 550 from each side

2750-550=2200

so the left over equation is:

2200 = 125x

3) divide each side by 125 to get x by itself

2200÷125= 17.6

4) you are left with: x = 17 days

|x|= 0.25
What value(s) of x make(s) the equation true?
A. -0.25 only
B. 0.25 only
C. 0.5 only
D. -0.25 and 0.25
E. -0.5 and 0.5

Answers

answer: d. -0.25 and 0.25
explanation: the absolute value bar means that any number put into there will be the positive version no matter its original value. therefore, the absolute value of -0.25 and 0.25 is 0.25.

Cheryl wants you find the number of hours 7th graders do work at home each week. There are 297 boys and girls in 7th grade, Cheryl random surveyed 50 girls in the entire school to find a number of our 7th graders do homework each week described why she would get a biased sample​

Answers

Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.

(FULL CREDIT TO maksimylian, I DID NOT WRITE THIS ANSWER)

Answer:

Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample.

The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population.

The results would not be a representative sample of the population.
