Answer:
Option B is correct.
16a +20 is the expression equivalent to \(4(4a+5)\)
Step-by-step explanation:
Given the expression: \(4(4a+5)\) .....[1]
The distributive property says that:
\(a \cdot (b+c) = a\cdot b + a\cdot c\)
Apply the distributive property in [1] we get;
\(4(4a+5)\) = \(4 \cdot (4a) + 4 \cdot (5) = 16a + 20\)
Therefore, the expression which is equivalent to \(4(4a+5)\) is, 16a + 20
