Answer:

Step-by-step explanation:

b = a^2/4 +4

Let a =8

b = 8^2 /4 +4

= 64/4 +4

= 16 +4

= 20

Answer:

b = 20 when a = 8.

Step-by-step explanation:

For this problem, we will simply plug the value of a=8 into the given equation for b, to find the value of b.

b = [ (a)^2 / 4 ] + 4

b = [ (8)^2 / 4 ] + 4

b = [ 64 / 4 ] + 4

b = [ 16 ] + 4

b = 20

Hence, when the value of a=8, then the value of b=20.
