Answer 2

Answer:

We will get the value is 23.

Step-by-step explanation:

• As per the question we have to evaluate the given data.

        Given data:- x=2.

        To find:- Value of 3x(4x-5)+5.

        Solution:-

• To solve the above question we will follow the BODMAS rule.

• BODMAS is an order of mathematic operations.

• It stands for,

          B= bracket

           O= order of power or rules

           D= division

           M= multiplication

           A= addition

           S= subtraction

     Now put the value of x=2 in 3x(4x-5)+5.

         $3x(4x-5)+5\\=3(2)(4(2)-5)+5\\=6(8-5)+5\\=6(3)+5\\=18+5\\=23$
