Answer:
21 cm by 21 cm
Step-by-step explanation:
The formula for the area of a square is A = x^2, where x is the length of any one side of the square. Here,
441 cm² = x²
This actually has two roots: {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.
The dimensions of the square are 21 cm by 21 cm.
.5 or 1/2 because when you divide each side by 2 you get the equivalent to the length of that certain side
The answer for this is the rules is x n y
Answer:
a=1
Step-by-step explanation:
7(5a-4)-1=14-8a
Distribute
35a - 28 -1 = 14 -8a
Combine like terms
35a -29 = 14 -8a
Add 8a to each side
35a+8a -29 = 14 -8a+8a
43a -29 = 14
Add 29 to each side
43a -29+29 = 14+29
43a = 43
Divide each side by 43
43a/43 = 43/43
a =1
