The answer is: "10 cm" .
____________________________________
Method 1)
____________________________________________
2L + 2w = 40 ; Since the formula for perimeter of a rectangle (Note: a square is a rectangle) is:
P = 2L + 2w ; Note: L = length; w = width; P = perimeter;
______________________________________________________
Factor out a "2":
_________________
" 2L + 2w = 40" ;
2 (L+ w) = 40;
Divide each side of the question by "2" ;
____________________________________
[2 (L + w)] / 2 = 40 / 2 ;
____________________________________
to get: (L + w) = 20 ;
Note: this "rectangle is a square" ; so L= w".
__________________
20 /2 = 10 ;
L + w = 10 + 10 = 20.
This is a square, so each side of the square is the same length.
Each side is: 10 cm .
______________________________________________
Method 2)
______________________________________________
We are given: The perimeter (sum of the lengths of all sides) of a square is "40 cm." Since a square has 4 sides of equal length:
Each side is: 40 cm / 4 = 10 cm.

Answer:
GL = square root of 2 = √2
Step-by-step explanation:
Given: GHJK is a square and its diagonals intersect at L
GJ and HK are its two diagonals.
We know that in a square diagonals bisect each other and if length of side is a, then length of its diagonal = √2 a.
Therefore, GJ=HK = √2×2
Since, diagonal intersect at L , L is mid point of GJ and HK
Therefore, GL = √2×2/2 = √2
Hence, GL = square root of 2
Answer:
I love algebra anyways
the ans is in the picture with the steps
(hope it helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Which of the following sequences are not geometric? (check all that apply) a. 2,10,50,250,1250 b. 1,4,9,16,25,36 c. -4,-2,-1,-0.
Romashka [77]
A is geometric because each number is multiplied by 5.
B is not geometric because it is an arithmetic sequence.
C is a geometric sequence because each number is divided by 2.
D is neither geometric not arithmetic because there is no common ratio and there is not a pattern being added or subtracted to each number.
So, your answer should be B and D.
Its 5 because if u do 3x 5 it equals 15 then subtract 2 it gives u 13
