Answer:
B. 4.5
Step-by-step explanation:
Since the are similar quadrilaterals, their side lengths are in proportion to each other.
Look at the letter ordering, ABCD and EFGH, the represent corresponding points in the quadrilateral, so
BC and FG are the same corresponding side of the quadrilateral. For the first quadrilateral, A is the first letter, B is the second. In the second quadrilateral, E is the first letter, and F is the second. A corresponds to E, and B corresponds to F. The rest of the letters correspond the same way
as are CD and GH
So we have a proportion, "CD is to GH as BC is to FG"
We have values for all sides in our proportion except FG, so plug them in...
CD =4, GH = 6, BC = 3 and FG is unknown,
4/6 = 3/FG
Solve for FG by cross-multiplying (here FG is one variable)
4FG = 18
FG = 18/4
FG = 4.5
Step-by-step explanation:
5 log₅ x − ¼ log₅ (8−x)
log₅ x⁵ − log₅ (8−x)^¼
log₅ x⁵ − log₅ ∜(8−x)
log₅ (x⁵ / ∜(8−x))
Remember that the difference between census and a sample survey is that in a census you take all the people of population in consideration in the study, and in the sample survey you take a part of that population in consideration to survey.
SO here if you check the problem it says that "in a recent poll, Pew reserchers found that 47% OF AMERICAN ADULT RESPONDENTS"
that is the population of the study that you want to focus, but there are a billion of american adult in US right? so its impossible that this company Pow Research made a census if you consider that a billion of people in US is almost infinite number for a company with a finite number of employees.
Also remember that a company has a budget to consider every month or every year, so to make a census or a sample survey it takes time and money, just to survey 10 people in a streeth of US cost money so if you want to reduce cost you might need to do a sample survey instead of a census.

Answer:
x = 2 2/3 is the solution; x = 2 is not a solution.
Step-by-step explanation:
The solution is ...
3x +4 = 12 . . . . . . given
3x = 8 . . . . . . . . . .subtract 4
x = 8/3 = 2 2/3 . . . divide by 3
x = 2 is not a solution. The correct solution is x = 2 2/3.
