➷ You can test it out using Pythagoras' theorem
c^2 = a^2 + b^2
Substitute in the values:
c^2 = 5^2 + 12^2
c^2 = 169
Square root it:
c = 13
No, this isn't a right angles triangle

Answer:
x = 53/9
Step-by-step explanation:
9 x - 2×(8) = 37
9 x - 16 = 37
9 x = 37 + 16
9 x = 53
x = 53/9
Answer:
If this is asking you to simplify, it's easiest to focus on one thing at a time and taking your steps slowly.
Step-by-step explanation:
First, put each letter variable in an organized manner to help yourself simplify (this isn't required, but it's helpful):
- 5ck - ck + 4c + 8k + 1
Then, take it slowly and simplify/combine the like terms:
- 6ck + 4c + 8k + 1
Hopefully that was the answer you were looking for!
Volume is legnth times width times height
if legnth=width=height and legnth=13
volume=13 times 13 times 13
exponents tell how many times to multiply by itself
2^3 means 2 times itself 3 times or 2 times 2 times 2
so 13 times 13 times 13=13^3
so the answer is 13^3
