So the problem ask to find an indirect proof to show that opposite sides of a parallelogram are congruent. So if we want to prove that a rectangle has a vertexes of ABCD where as to prove that AB=CD, lets start by proving it using AB is not equal to CD nad forming a parallelogram and the lines that bisect each side can prove that AB=CD
The statement "y varies inversely as x means that when x increases, y decreases by the same factor. In other words, the expression xy is constant :
x*y = k
k is the variation constant.
Just substitute the values in that formula :
16*9 = 4*4*9 = 172.
So the variation constant here is 172.
In order to find the equation of variation of y, you should change the equation i gave you.
y = k/x
y= 172/x
Hope this helps !

The factored form of the given expressions are
y = (x -2)(x +7)
y = (x +6)(x -9)
y = (x +2)(x +6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = (x -1)(x +9)
y = (x +4)(x -4)
<h3>Factoring quadratic expressions</h3>
From the question we are to factor the given quadratic expressions
y = x² +7x -2x - 14
y = x(x +7) -2(x +7)
y = (x -2)(x +7)
y = x² -9x +6x - 54
y = x(x -9) +6(x -9)
y = (x +6)(x -9)
y = x² +6x +2x +12
y = x(x +6) +2(x +6)
y = (x +2)(x +6)
y = x² -6x -5x +30
y = x(x -6) -5(x -6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = x² +9x -x -9
y = x(x +9) -1(x +9)
y = (x -1)(x +9)
y = (x +4)(x -4)
Hence, the factored form of the given expressions are
y = (x -2)(x +7)
y = (x +6)(x -9)
y = (x +2)(x +6)
y = (x -5)(x -6)
y = (x +5)(x -5)
y = (x -1)(x +9)
y = (x +4)(x -4)
