Answer:

The quadrilateral shown is a kite, because it has two non-congruent pairs of congruent sides

x = 3

Step-by-step explanation:

The vertex angles in a kite are bisected by the diagonals. Thus, 11x = 9x + 6.

11x=9x+6

2x=6

x=3

Answer:

${ x^2+3x-4}$

Step-by-step explanation:

Factor top and bottom.

The numerator is a difference of two squares, and the denominator is a quadratic.

$\frac{ {9x}^{2} - {(x}^{2} - 4)^{2} }{4 + 3x - {x}^{2} }$

= $\frac{ (3x+x^2-4)(3x-x^2+4) }{(1+x)(4-x)}$

= $\frac{ (x-1)(x+4) (1+x)(4-x) }{(1+x)(4-x)}$

If x does not equal -1 and does not equal 4, we can cancel the common factors in italics to give

= ${ (x-1)(x+4)}$

= ${ x^2+3x-4}$

7 of 1010 PointsThat is the multiplicity of each of the roots of the graph of f(x) = 2x + 12r³ +16r² - 12x - 18?-3, multiplicity

Paul [167]

Solution:

Given the function;

$f(x)=2x^4+12x^3+16x^2-12x-18$

The graph of the function is;

Thus, the multiplicity of each of the roots of the graph is;

$\begin{gathered} -3,multiplicity\text{ }2; \\ \\ -1,multiplicity\text{ }1; \\ \\ 1,multiplicity\text{ }1 \end{gathered}$
