10p - 5c + 2p + 8c
= 10p + 2p - 5c + 8c
= (10+2)p + (-5+8)c
= 12p + (8-5)c
= 12p + 3c
5x6-5<-------
5x6=30
30-5=25
there you go (The first expression is the answer-hope it helps!)
Answer:5 and 92
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
I am amusing you are looking for the hypotenuse since this is middle school.
If you have the legs and are looking for the hypotenuse you use the Pythagorean Theorem ![a^{2} + b^{2} = c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
The legs are a and b, and the hypotenuse is c
The work would look like this
![13^{2} + 5^{2} = c^{2} \\169+25= c^{2} \\194= c^{2} \\\sqrt{194} = \sqrt{c^{2} } \\13.9283883... = c](https://tex.z-dn.net/?f=13%5E%7B2%7D%20%2B%205%5E%7B2%7D%20%3D%20c%5E%7B2%7D%20%5C%5C169%2B25%3D%20c%5E%7B2%7D%20%5C%5C194%3D%20c%5E%7B2%7D%20%5C%5C%5Csqrt%7B194%7D%20%3D%20%5Csqrt%7Bc%5E%7B2%7D%20%7D%20%5C%5C13.9283883...%20%3D%20c)
extra notes
- I rounded to 13
- If you didn;t know you cancles exponents with roots
so the
is cancled by aka
Hope this helped :)
The answer should be option D.
Because natural number can be negative .
