Answer:
(x+1)(x-2)(x-3)^2
Step-by-step explanation:
Sorry, mate. That math is too hard to type out online. You's guys will just have to take my word for it!

Here is your answer and an explanation
Answer: y = -2/3x
Explanation:
This can be determined by calculating the gradient of the straight line, using:
m=ΔyΔx
=−6−34−(−2)
=−96
=−32
Then we use the slope-point form of the straight line:
y−y1=m(x−x1)
to give:
y−3=−32(x−(−2))
∴y−3=−32(x+2)
∴y−3=−32x−3
∴y=−32x
Answer: C. 6
Therefore, 6 machine R was used.
Step-by-step explanation:
Given;
Time taken for machine R = 36 hours
Time taken for machine S = 18 hours
The fraction of work completed by machine R and S in 1 hour is ;
R = 1/36
S = 1/18
Let n represent the number of each type of machine used to do the job.
Time taken for n machine R and S is 2 hours.
The fraction of job completed by n Machine R and S is;
n(R +S) = 1/2
Since R = 1/36 and S = 1/18
n(1/36 + 1/18) = 1/2
n = 1/2/(1/36 + 1/18)
n = 6
Therefore, 6 machine R was used.
