You have to subtract 3x + 18 from 5x - 12:
=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30
The first step was to apply distributive property to supress the parenthesis, after that the terms were arranged and the like terms combined.
Answer: 2x - 30

Answer:
P-value ≈ 0.3463
Step-by-step explanation:
Hypothesis test would be
:p=0.20
:p>0.20
We need to calculate the z-score of sample proportion and then the corresponding P-value.
z-score can be calculated as:
z= where
- p(s) is the sample proportion of specimens yield before the theoretical point ()
- p is the proportion assumed under null hypothesis. (0.20)
- N is the sample size (40)
Using the numbers
z= =0.3953
and the P-value is then P(z)≈0.3463
