Answer:
See below
Step-by-step explanation:
We can make a the number of days and y the number of workers
Since we were told there is an inverse relationship between the days required to build the house and the number of workers required, then,
The equation would be
y = k/x
Here, y is inversely proportional to x and k is the constant proportionality
So, out required equation would be
a = k/n
Fixing the values, we'll have
55 = k/8
k = 55 × 8
k = 440
The number of days required to build a similar house with 5 workers will now be
= 440/5
= 88 days
There are enough information's already given in the question. Based on those information's that answer can be easily deduced.
Radius of the sphere = 8 units
Then
Surface area of the sphere = 4 *pi * r^2
= 4 * pi * (8)^2
= 4 * pi * 64
= 256pi
I hope that this answer has come to your help.

Answer:
Step-by-step explanation:
(x+3)(x+3)
distribute the x to both three and x.
x * x + 3x * 3x
add like terms.
X^2 + 9x
