Answer:
x ≤ 6
Step-by-step explanation:
5x - 9 ≤ 21
Step 1. Add 9 to both sides
5x ≤ 30
Step 2. Divide it all by 5
x ≤ 6
Answer:
x2-x1/y2-y1=2-4/10--2=2-4/10+2=-2/12
=-6

Answer:
Another term for an equilateral triangle in geometry is equiangular or a regular triangle
Step-by-step explanation:
I do not know what you mean by the wording of some of these questions, so I will just give you the formula and tell you how to apply it. The formula of the Pythagorean Theorem is a^2 + b^2 = c^2. a and b are the two sides adjecent to the right angle (in the corner). c is the side opposite the right angle. So, to get c you would have to add sides a and b but with each of them to the second power. Then, you would find the square root of the sum (you can do this with a calculator). To find sides a or b, subtract a or b (whichever one available) to the second power from c to the second power. Then find the square root of the sum. That is all I know how to do, so combine this knowledge with yours to see if you can solve it. If you have any questions about what I already know, feel free to ask. You can also ask for an example. If you have a question about something that I have not explained, look it up on the internet, or hopefully you can find someone who can help you. I hope this helps.
