Answer:

C. 4i

Step-by-step explanation:

$\sqrt{-16} = \sqrt{16} \sqrt{-1}$ (because $\sqrt{ab} =\sqrt{a} \sqrt{b}$ )

Since $\sqrt{16}$ =4, and $\sqrt{-1}$ =i, $\sqrt{-16}$ =4i

evablogger [386]

$\left\{\begin{array}{ccc}y=-7x+2\\y=9x-1\end{array}\right\Rightarrow 9x-1=-7x+2\\\\9x-1=-7x+2\ \ \ |+1\\9x=-7x+3\ \ \ |+7x\\16x=3\ \ \ \ |:16\\x=\dfrac{3}{16}\\\\\text{substitute the value of x to the second equation}\\\\y=9\cdot\dfrac{3}{16}-1\\\\y=\dfrac{27}{16}-\dfrac{16}{16}\\\\y=\dfrac{11}{16}\\\\\text{The solution is}\ \left(\dfrac{3}{16};\ \dfrac{11}{16}\right)$

Answer:

Step-by-step explanation

I'd say it's PQR and TSR cause they match up in terms of the order of vertexes, and then you've got the angles of P and T that are in the middle of PR and TR, which are equal, and the sides PQ and TS. The angles are in between the sides.
