The perimeter of a square is calculated by the formula ( P = 4 \times \text{side length} ). Given that the length of the side is ( 2x - 1 ), the perimeter can be expressed as ( P = 4(2x - 1) ). Simplifying this, we get ( P = 8x - 4 ). Thus, the perimeter of the square in terms of ( x ) is ( 8x - 4 ).
No, the square root of 8 is not 4. The square root of 8 is approximately 2.83, since (2.83 \times 2.83 \approx 8). In exact terms, it can be expressed as (2\sqrt{2}).
No, an irrational number is, in simple terms, a number that keeps repeating. The square root of 4 is positive or negative 2, which does not repeat and is therefore rational.
The square root of [ sqrt(40) ] = 40(1/4) = plus or minus 2.5149 (rounded)

No, ( m^2 - 4m - 4 ) is not a trinomial square. A trinomial square takes the form ( (a + b)^2 = a^2 + 2ab + b^2 ), which means it must have a perfect square as its first and last terms and a middle term that is twice the product of the square roots of those terms. In this case, the expression does not fit that pattern due to the negative constant term and the linear term not matching the required form.
It has a square base.
Measure its side in terms of feet. Multiply that measure by itself to give the area in square feet.
It is Russia, with 6,592,771 square miles.
