Answer:
11xy^4(y+7x)
Step-by-step explanation:
The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2

This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
The statements are true about the residual plot and the equation for the line of best fit include:
- The equation for the line of best fit is not a good approximation for the data because the points have a curved pattern.
- The residual plot has the pattern of a curve.
<h3>
What is Residual plot?</h3>
This shows the residuals on the vertical axis and the independent variable on the horizontal axis.
Since the plot has a curved pattern, the equation for the line of best fit is not a good approximation for the data as the result will be inaccurate.
