The expression that is equal to 3B - C in standard form is 2.0 × 10¹
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
