Solve for x
We have:

Collect like terms

Multiply through by 

Make x the subject

Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9
Answer:
We would have

where " l " is length, " w" is width and "h" is height.
Step-by-step explanation:
Step 1
Remember that
Surface area for a box with no top = 
where " l " is length, " w" is width and "h" is height.
Step 2.
Remember as well that
Volume of the box = 
Step 3
We can now use lagrange multipliers. Lets say,

and

By the lagrange multipliers method we know that

Step 4
Remember that

and

So basically you will have the system of equations

Now, remember that you can multiply the first eqation, by "l" the second equation by "w" and the third one by "h" and you would get

Then you would get

You can get rid of
from these equations and you would get

And from those equations you would get

Now remember the original equation

If we plug in what we just got, we would have

The probability of he/she is a technician or production operator will be 7/8.
<h3>What is probability?</h3>
The probability of an event occurring is defined by probability.
If you flip a coin, the likelihood that it will land on its head or tail is nothing more than the chance that either the head or the tail will occur.
Given,
Event 1 = selection of technician
Event 2 = selection of production operator
Since both events are independent and nothing has common in between
So,
P(1 or 2 ) = p(1) × p(2)
So,
probability (technician or production operator) = probability of technician × probability of production operator.
Probability (technician or production operator) = 10/40 + 25/40 = 7/8
Hence the probability of he/she is a technician or production operator will be 7/8.
