Answer:
(1) If the GCD of 5 and 12 is 1, then they are co-prime.
(2) The sum of 5 and 12 is 7 if and only if 5 is a negative integer.
Step-by-step explanation:
(1)
The GCD (greatest common divisor) of two or more numbers, which are not all equal to zero, is the largest positive integer number which divides each of the numbers.
If the GCD of two numbers is 1, then the two numbers are known as coprime or relatively prime or mutually prime.
(2)
The sum of 5 and 12 is 7 if and only if, the number 5 is a negative integer, i.e.
-5 + 12 = 7
Answer: if you are referring to a right triangle the third side might be 20.5cm
Step-by-step explanation:
I just used Pythagorean theorem in which c^2=a^2+b^2
so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm
Hope I helped
Pdt: a=15 b=14
the answer would be B. I used m a th way to find out what the answer was, you could use that app if you ever come across a similar question!
Your discriminant is a negative number. Therefore, your solutions are imaginary. It's d from above.
No it isn't because on the last one 50÷15 is 3.5 and on the other's you got just 3 as the constant
