4.2 is a pure real (rational) number. It has no specific X value.
The value of 42 squared is 1,764. This is calculated by multiplying 42 by itself (42 x 42), resulting in 1,764.
42
The expression "7 times something minus 42" can be mathematically represented as ( 7x - 42 ), where ( x ) is the "something". This means you multiply the value of ( x ) by 7 and then subtract 42 from the result. The specific outcome will depend on the value of ( x ).
6
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 value of 42 squared is 1,764. This is calculated by multiplying 42 by itself (42 x 42), resulting in 1,764.
The answer will depend on the value of x. If x is a square number, then the answer is 42,If x is a factor of 42 then it is 42/x,Otherwise it is 42*x.

If that's supposed to be a multiplication, the "x" doesn't have a value - it's an operator. The whole expression, on the other hand, does have a value (just do the multiplication).If the "x" is supposed to be an exponent, then it doesn't have a specific value; that is, it may have any value.
If you mean: 3(2+4x) = 42 then the value of x works out as 3

-42
This can be written as 16 + x = 42. We know that x, or your "something" is exactly 16 less than 42. All you would have to do to solve it would be to subtract 16 from 42. 42-16=26 so your x value is 26.
