Answer:
-19
well i think it the answer
2.159 • 10⁴⁵
you move the decimal point until you get a one digit decimal.
Answer:
a) The domain is the set of the possible values of x.
In the graph, we can see that x goes from - 4 to 4
So the domain is: D = x∈ {-4, 4)
b) The zeros are the points where the graph cuts the x-axis.
Those values are:
x = -2
x = 0
x = 2.
c) The graph is positive if it is above the x-axis and it is negative if it is below the x-axis.
in the interval {-4,0} the graph is bellow the x-axis, so in this interval the function is negative.
in the interval {0, 2} the graph is above the x-axis, so in this interval the function is positive.
in the interval {2, 4} the graph is bellow the x-axis, so in this interval the function is negative.
Sorry I couldn't find this sooner!
The perimeter of any polygon means the sum of all the lengths of its sides. In this case the sides are (5x - 2), (2x - 3), and (4x + 3). We can find the perimeter by adding all of these lengths up:
(5x - 2) + (2x - 3) + (4x + 3)
= 5x - 2 + 2x - 3 + 4x + 3
=11x -2
Final Answer: B. 11x - 2
