Answer:
x=8
Step-by-step explanation:
3x-4+2x=36
5x-4=36
5x=36+4
5x=40
8x5=40
Yes, Ranger was right that expression 8x-20 can be simplified further as 4(2x-5).
The given expression is 8x-20.
Ranger says the expression is not in its simplest form. He thinks the two terms need to be combined.
Yes Ranger is correct, the given expression can simplified further.
That is, 8x-20
Factors of 8x and 20 are
8x=2×2×2×x
20=2×2×5
So, the common term is 4
Now, 8x-20=4(2x-5)
Yes, Ranger was right that expression 8x-20 can be simplified further as 4(2x-5).

because a quarteratrall is a shape with 4 sides a rhombus has 4 sides a trapezoidal has 4 sides and a paralleagram two be a shape it has to have four sides or else it wont be a parallel
Answer:
C
Step-by-step explanation:
Does the residual plot show that the line of best fit is
appropriate for the data?
A. Yes, the points have no pattern.
B. Yes, the points are evenly distributed about the x-axis.
C.No the points are in a linear pattern.
D.No, the points are in a curved pattern.
Answer: it’s option C: No, the points are in a linear pattern
Step-by-step explanation:
Took on edge
To determine if the line of best fit is appropriate for the data, plot the residuals on a graph and examine the pattern. In this case, the residual plot does not show a linear or curved pattern, indicating that the line of best fit is not appropriate for the data.
The residual plot shows the difference between the observed Y-values and the predicted Y-values. To plot the residuals, subtract the predicted Y-values from the observed Y-values for each corresponding X-value. Then plot the resulting points on a graph. In this case, the points are:
(1, 0.86), (2, -0.25), (3, -1.66), (4, -2.34), (5,-4.1).
To determine if the line of best fit is appropriate for the data, we need to examine the pattern of the residual plot. If the points have no pattern or are evenly distributed about the x-axis, it indicates that the line of best fit is appropriate. In this case, the points do not exhibit a linear or curved pattern, and they are not evenly distributed about the x-axis. Therefore, the residual plot does not show that the line of best fit is appropriate for the data.
Hence, the correct answer is: C. No the points are in a linear pattern.
