Answer:
m=-1
Step-by-step explanation:
9m+13 =4
Subtract 13 from each side
9m+13-13 =4-13
9m = -9
Divide each side by 9
9m/9 = -9/9
m = -1
To find length and width you need to factor 3x² - 10x - 8. The final factored form will be (3x+2)(x-4).
Work:
Use the distance formula to find the length of the sides, then add them up to find the perimeter.

For points in the form of (x1, y1), (x2, y2).
(-1, 2), (3, 1)




(3, 1), (7, 2)




(7, 2), (-1, 2)




So the perimeter will be:
An open shape is made up of line segments. In this type of shape there is at least one line segment that is not connected to anything at one of its endpoints, so the shape is not a closed figure. So, I am going to provide four graphs for this problem.
1. Parable
This is given by the curve:

See figure 1.
2. Cubic function.
This function is given by:

see figure 2
3. Quartic function
This curve is given by:

see figure 3
4. Cosine functionThis function is given by this equation:

See figure 4.
All these curves are open shapes. So, we can find a new open shape as the sum of all these curves as follows:

See figure 5.
Answer: Kahn is wrong because the sequence increases by 5 after every number. The next two numbers in the sequence would be 28, 33. Kahn puts 29, 33 which is incorrect.
