You can use the property of distribution of multiplication over addition.

The expression that is equivalent to 48 + 12 is

Option B: 12(4 + 1)

How is multiplication distributive over addition?

Suppose you've got $a \times (b + c)$, then you can distribute in those two numbers inside the bracket in multiplication as:

$a \times (b + c) = a \times b + a \times c$

How to get the equivalent expression for 48 + 12 from given option?

Since 48 is 12 times 4 and 12 is 12 times 1, then we have:

$48 + 12 = 12 \times 4 + 12 \times 1 = 12 \times (4 + 1)\\\\48 + 12 = 12(4 + 1 ) \text{\: (The multiplication sign is not written but is assumed to be there})}$

Thus ,the expression that is equivalent to 48 + 12 is

Option B: 12(4 + 1)
