Answer:

17*2^11

Step-by-step explanation:

Lets start by remembering two property of power.

$x^{m} * x^{n}= x^{n+m}$

$(x^{m})^{n}= x^{m*n}$

That is important to remember since 4= 2^2. Hence, the given problem can be written as the following

$-2*(2^{2} )^{5}+9*2^{2}*(2^{2} )^{5} \\-2*2^{10}+9*2^{2}*2^{10}\\ -2^{11}+9*2^{12}\\ -2^{11}(-1+9*2)=-2^{11} (17)$

<h2>Step-by-step explanation:</h2>

$\left\{\right.{ \triangle}\ RST\cong { \triangle}\ DE$ F

$(SSS\ Congruence\ Postulate)$

$2.\ { \triangle\ CAT\cong { \triangle\ BED\ \left\{\right.Given\left.\ \right\}$

$\bar{AT}\cong\bar{ED}$

$\overline{AT}=20$

$so\ \overline{ED}=20$

$DE=3x-7=20\rightarrow\ x=9$
