8x - 2(x + 1) = 2(3x - 1)
First, expand to remove parenthesis. / Your problem should look like:
Second, subtract 8x - 2x - 2 to get 6x - 2. / Your problem should look like:
Third, both sides are equal, so there are infinite solutions. The equation is always true.
Answer: infinite solutions

Answer: infinite solutions
bolts of length more than , and less than
will be destroyed
= 13.20 cm and 12.80 cm
<u>Step-by-step explanation:</u>
Here we have , A manufacturer of bolts has a quality-control policy that requires it to destroy any bolts that are more than 2 standard deviations from the mean. The quality-control engineer knows that the bolts coming off the assembly line have mean length of 13 cm with a standard deviation of 0.10 cm. We need to find For what lengths will a bolt be destroyed .Let's find out:
A manufacturer of bolts has a quality control policy that requires it destroy any bolts that are more than 2 standard deviations from the mean.
mean length=
standard deviation=
2 standard deviation from mean=
Therefore, bolts of length more than , and less than
will be destroyed
= 13.20 cm and 12.80 cm
Answer:
By using the formula of the octagon:
10m=1000cm
A ≈ 4.83×10^6 cm²
