Answer:
Simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
Step-by-step explanation:
As the expression given in the question be as follow .
= (x−3)( x²−4x−7)
simplify the above
= x (x²-4x-7)-3 (x²-4x-7)
Now open the bracket
= x³ - 4x² -7x - 3x² + 12x + 21
= x³- 4x²-3x²-7x + 12x + 21
= x³ -7x² + 5x + 21
Thus the simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .

A scatter plot shows the association between the variables it measures
The association shown on the graph between x and y is (d) No association
<h3>How to determine the association</h3>
From the graph, we can see that the points on the plot are scattered, and they do not follow any pattern
This means that, there is no association between the x and y variables
Hence, the true statement is (d) No association

Answer:
<u>40%</u>
Step-by-step explanation:
because there is 10 parts and if the 10 multipied by 10 (to find the percent) is 100 then the 4 is 40 (the unshaded part would be 60%)
Have a fantastic day!
First you can measure it with a ruler. From what I see it seems like half.
6 divided by 2 = 3ft
