The simplified form of the given expression is 2015
<h3>Simplifying expressions </h3>
The given expression is (x-2)(x+2)(x²+4)-(x²+3)(x²-3)+2022
The expression can be simplified as shown below
(x-2)(x+2)(x²+4) - (x²+3)(x²-3) + 2022
x(x+2)-2(x+2)(x²+4) - x²(x²-3) +3(x²-3) + 2022
(x²+2x-2x-4)(x²+4) - (x⁴-3x²+3x²-9) + 2022
(x²-4)(x²+4) - (x⁴-9) + 2022
x²(x²+4) -4(x²+4) - (x⁴-9) + 2022
(x⁴+4x²-4x²-16) - (x⁴-9) + 2022
(x⁴-16) - (x⁴-9) + 2022
x⁴ -16 -x⁴ +9 + 2022
x⁴ -x⁴ -16 +9 +2022
= 2015
Hence, the simplified expression is 2015

Answer: a. 0.9876
Step-by-step explanation:
Given : The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1 kg.
and 
sample size : n= 25
Let x denotes the total body protein in healthy adult men in the sample.
Then, the probability that their average total body protein is between 12.25 and 12.35 kg will be :-

∴ The correct answer is a. 0.9876
Answer:

And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:


And now we can divide both sides by 5 and we got:

So then the number of hours spent to decorate the house are 25
Step-by-step explanation:
Based on the information given we can model this function with this formula:

Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:

And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:


And now we can divide both sides by 5 and we got:

So then the number of hours spent to decorate the house are 25
Answer:
32 times
Step-by-step explanation:
1/8 x 8= 1
1/8 x 32= 4
X equals 4 because 2 times 2 equals 4 and then 4 times 4 =16
