< A square has 4 sides that are all always equal to each other. The perimeter is all the sides summed up together. That means (for example), if one side of the square is 2 cm, then we know that the perimeter is 8 cm, because 2 + 2 + 2 + 2 = 8 (or 2×4=8).

Here we are given that one side is equal to "x-5". Pretend that is a number and solve as I did just right above:

(x-5)×4 = 4x -20

Now we know that the perimeter is (4x-20) units (when you don't know what the units are then just put "units").

We also know that the perimeter can be a number which is 24. That means these two values are equal to each other.

4x-20 = 24

Now solve! Bring x to one side, and all the numbers to the other side.

4x = 44

x = 11

We now know that the value of one side of the square (x) is equal to 11 units. >

Hope this helped! Feel free to ask anything else.

8, 12, 16, ... Find the 49th term

Ivanshal [37]

Answer:

200

Step-by-step explanation:

the above is an arithmetic progressions

number of terms of an AP = a+( n -1 )d

a= first term= 8

d= common difference= 12-8= 4

49th term:

= 8+(49-1)4

= 8+(48)4

= 8+192= 200

therefore, the 49th term is 200
