Answer:
a
Step-by-step explanation:
(3x-14)+9x=90, thus,
((3x-14)+9x)+90=180
90+90=180
Part A)The given equation is:
The radicand or discriminant(d) of the equation will be:
Since the discriminant is equal to 0, the given quadratic equation has only 1 root. In other words we can say the the given equation is a perfect square.
Part B)The given equation is:
We can solve this expression by factorization. Factors of middle term are to be made in such a way that their product equals the product of first and third term and sum is equal to the middle term i.e. product should be 4x² and sum should be -4x.
So the two such terms are -2x and -2x. Using the factors and simplifying the equation by taking common we get:
To find the value of x , bring the variable to the left side and bring all the remaining values to the right side. simplify the values to find the result.
Though the box plot is not given, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.
<h3>What is a box plot?</h3>
A box plot gives a graphical (rectangular) representation of statistical data based on the following five values: minimum, first quartile, median, third quartile, and maximum.
Essentially, a box plot has the following five data descriptions:
- The leftmost whisker, showing the minimum value.
- The rightmost whisker, showing the maximum value.
- The leftmost line, showing the first quartile.
- The middle line, showing the median or the second quartile.
- The last line shows the third quartile.
Thus, the truth about the data set represented by the box plot is <u>removing</u> the outliers would not affect the median.

Answer:
x = 23.1
Step-by-step explanation:
The parallel lines make the left segments proportional to the right segments. This lets us write the equation ...
x/14 = 33/20
Multiplying by 14, we get ...
x = 14(33/20) = 7(33/10) = 23.1
