A cube is a number that can have another number be multiplied by itself three times to equal the cube. A cube root is the number that is multiplied by itself three times. Example: 8 is a cube because 2 x 2 x 2 = 8 and 2 is the cube root. I hope this helped :)
Answer: 5
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
x^2 = 25
square root both sides
x = 5
to check, do 12^2 + 5^2 =169
sqrt of 169 is 13
