Answer:
B. [tex](4x-5)[/tex]
Step-by-step explanation:
We are given that,
Area of the square design = [tex]16x^2 -40x + 25[/tex] inch²
Factorizing the polynomial, we see that,
[tex]16x^2 -40x + 25=0[/tex]
implies [tex](4x-5)^2=0[/tex]
So, the factors of the polynomial are [tex](4x-5)[/tex] and [tex](4x-5)[/tex]
That is, [tex]16x^2 -40x + 25=0[/tex] = [tex](4x-5)^2=0[/tex].
Thus, we have,
Area of the square design = [tex]16x^2 -40x + 25[/tex] = [tex](4x-5)^2[/tex]
As, Area of a square = [tex]Side^2[/tex]
Hence, on comparing the sides of the square design are [tex](4x-5)[/tex].
So, option B is correct.
