If floor of a square office is 256 square units what is the perimeter

If the area of the square is equal to 256 centimetres squared, then each side of the square would be sqrt(256) = 16.

Therefore, given that a square has four sides of equal length, the perimeter of the square would be 16 x 4 = 64 centimetres.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
