Similarities: They both are polynomials of degree 2, both of their graphs is a parabola, both have either 2 or 0 real solutions, they are both continuous functions over R
<span>(DOS= difference of two squares, PST=perfect square trinomial </span>
<span>Differences: PST has three terms, whereas the difference of squares has 2. PST's factors are both the same, whereas DOS's elements are conjugates of each other. DOS can always be factored into two distinct polynomials with rational coefficients, whereas PST has two same polynomial factors.</span>
A=LW, we are told that the dimensions are 42 and 48 so:
A=42*48
A=2016in^2
Step-by-step explanation:
Center: (−7,4)(-7,4)
Radius: 7
The answer is n= -1.
Hope this helps
