The method of writing a number as product of two
factors is called​

 prime factorization.

Step-by-step explanation: When we write a number as a product of all its prime factors, it is called prime factorization. Every number in prime factorization is a prime number. Sometimes to write the prime factors of a number we might have to repeat

there are infinitely many solutions.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
