You have to know a great deal more about where Q and Q' are before you can say much of anything. The problem is listed a s a middle school problem so you are likely permitted to go by the way it looks, but that is not a habit that I would continue using.

So if the triangles SQR and S'Q'R' are congruent, and if they are orientated exactly the same way which means that the distance between QQ' and RR' is a constant (and those are big ifs), then you can claim that QQ' is parallel to the other two lines. Is it the same length as the other two? Again, you obtained the other two by measurement. It looks like SQR and S'Q'R' are equilateral and if that is correct then yes they lengths are all equal. But your marker could do just about anything with this question.

If you have a person marking this, talk it over with them. I say QQ' is equal and parallel to the other two, but don't be surprised if it is wrong.

I need help with math I tried my best but couldn’t get it

Answer:

Step-by-step explanation:

1. Convert to slope intercept form (y=mx+b)

2. Find slope (the 'm' in mx)

3. Find slope of perpendicular line

So for the first question:

Convert to slope Intercept form if necessary:

3x+4y=12

4y=12-3x<<Subtract by 3x

y=3-3/4x<<Divide by 4

Find slope

y=3-3/4x

3/4 is the slope

Find slope of perpendicular line

To find the slope of a perpendicular line, you just have to take the reciprocal of the original slope and take the opposite sign.

Here is what I mean:

3/4<<original slope

4/3<<reciprocal

-4/3<<opposite

So for the first question -4/3 is the answer.

Now you can do the rest! Hope this helps!

(If you have more questions feel free to comment to let me know!)

21 - 6 = x

so the answers is 15

21 - 6 = 15

check:
15 + 6 = 21
