Answer:
Step-by-step explanation:
4w+25=w^2+4w
So w =5
i think it is 8
27 x 2 = 54
A = 5.5t + 9
We assume that the relationship between t and A is linear.
We have two points on a line: (2, 20) and (4, 31).
We now find the equation of the line.
A = mt + b
m = (31 - 20)/(4 - 2) = 11/2 = 5.5
20 = 5.5(2) + b
20 = 11 + b
b = 9
