Answer:
Step-by-step explanation:
16^3 - 8^3
Take out 8^3 as a common factor.
16^3 = 2^3 * 8^3
8^3(2^3 - 1)
8^3(8 - 1) = 8^3 * 7
(4^3 + 2^3) Expand
64 + 8 Combine
72
72 = 9 * 8
Conclusion
(8*3 * 7 )(9*8)
7*9 = 63
So any number containing 63 will divide into the reduced form of
(16^3–8^3)(4^3 +2^3)
The percentage of the people surveyed that were satisfied with the car is 45%.
<u>Given the following data:</u>
- Total population = 1,600 people
- Number of car owner = 720 people.
To determine the percentage of the people surveyed that were satisfied with the car:
<h3>
How to solve for a percentage.</h3>
In this exercise, you're required to calculate the percentage of the total population in this survey that would by a particular type of car again because they were satisfied with it. Thus, we would solve for the percentage as follows;

Substituting the given parameters into the formula, we have;

Percent = 45%

Answer:
I think the answer is D
Step-by-step explanation:
X² - 7 x = - 5
x² - 7 x + 5 = 0
The standard form is : ax² + b x + c = 0
a = 1; b = -7; c = 5
x 1/2 = (-b+/- √(b²-4 ac) / 2a
x 1/2 = (7+/-√49 - 20) / 2 = ( 7 +/-√29 ) / 2
Answer: B ) 7 plus or minus the square root of 29 divided by two.
