Basically, in math the "mean" is a set of numbers that you add, then take the sum and divide it by how many numbers are in that set. Here is an example: 6, 7, 4, 5, 8, 9, 3. The sum of the numbers in this set is 42. However, there are 7 numbers in this set. So basically what you would do is take the sum of the numbers, 42, and divide it by the amount of numbers that are in this particular set, 7. So, 42÷7=6. So now you have figured out that the mean is 6. I hope this could be helpful!

A = 360 cm^2

Step-by-step explanation:

Using Pythagorean theorem, the length AB is given by

AB^2 = 17^2 - 8^2 = 225 cm^2

or

AB = 15 cm

Since the ratio BC: CD = 1:2 and BC = 8 cm, this means that CD = 2×(8 cm) = 16 cm

so the length BD is

BD = BC + CD = 8cm + 16 cm = 24 cm

There the area of the rectangle is

A = AB×BD

= 15cm×24cm

= 360 cm^2

Answer:

MNK = TRP

MN is congruent to TR.

X = 6.3

Step-by-step explanation:

MNK is congruent to TRP because the two triangles are congruent, which is a given statement. This also means that all side and angle measures will be congruent. Because of this, it can be inferred that MN is congruent to TR and they have equal side length measures. This means that TR measures 20. This means that 3X - 1 = 20. By solving we can get 6.33.
