Evaluating an expression

From the question, we are to determine the value of the expression

The given expression is

3B - C

From the given information,

B = p + 6

and

C = 3p - 2

Putting the the values of  B and C into the expression, we get

3B - C = 3(p + 6) - (3p -2)

= 3p + 18 -3p + 2

= 3p - 3p + 18 + 2

= 20

= 2.0 × 10¹

Hence, the expression that is equal to 3B - C in standard form is 2.0 × 10¹
