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