Answer: 
Step-by-step explanation:
The missing figure is attached.
The perimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.
You can identify in the figure that:

Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:

Now you must simplify and solve for "z"

Finally, substituting the value of "z" into
, you get:

So x is equal to 40 so the length of M and N is 140 and no is 70 with the total length being 210 hope I helped could I get a brainliest!!
Answer: 28 mins away
Step-by-step explanation: so i subtracted the time difference. if the called at 9:11 and it's now 9:39 subtract the times and you get 28 mins
Answer:
The polynomial would be x^4 - 5x^3 + 4x^2
Step-by-step explanation:
In order to find this, we need to take each answer and set it equal to x. Then we solve until it equals 0.
x = 4
x - 4 = 0
x = 1
x - 1 = 0
x = 0
x = 0
Now we have 4 of them and we simply multiply them all together.
(x)(x)(x - 1)(x - 4)
(x)(x)(x^2 - 5x + 4)
(x)(x^3 - 5x^2 + 4x)
x^4 - 5x^3 + 4x^2
