The solution follows A=42 42X42=1764 B=56 56X56=3136 sum of above=4900 (70X70=4900) Given you was looking for C and not C squared. Try A and B and doublecheck it for me.
42 + x2 = 13x ∴ x2 - 13x + 42 = 0 ∴ (x - 6)(x - 7) = 0 ∴ x ∈ {6, 7}
X = 5 or -5 3x2 - 42 = 33 3x2 = 75 x2=25
3060.
They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
It is: 2n^2 -5n -42 equals (2n+7)(n-6) when factored
A number squared is just that number times itself. For example four squared is four times four equals sixteen (42 = 4 x 4 = 16).

42 squared - or 42 x 42 is 1764
Answer: 42 m² = 452.084 ft²
The answer depends on what the question is!
It is a quadratic equation and the value of x is -7 or 6 x2 - 42 = (-x) x2 + x - 42 = 0 (x + 7) (x - 6) = 0
The number that equals 121 when squared is 11.
