I am thinking of two prime numbers. I can tell you their HCF.
I can tell you how to find their LCM.

a How can Sasha do that?
b What will Razi tell Jake?​

Prime numbers only have two factors which is 1 and itself so the HCF of a prime number is itself.

LCM of prime numbers is like the LCM of any other number. See where the lowest multiple of both prime numbers are equal.

Hope this helps.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
