Answer:
20
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.

Answer:
27
Step-by-step explanation:
We are given that a = -5 and y = 7 and we are asked to evaluate the expression -4a + y.
To evaluate the expression, we would plug -5 for a and 7 for y into the expression.
-4a + y = -4(-5) + 7 = 20 + 7 = 27
So -4a + y = 27.
