Answer:
10x - 20
Step-by-step explanation:
<em>Distribute 5 </em>to <em>each</em> of the terms within the parentheses to get 5(2x) - 5(4) = 10x - 20.

As we can see
![\\ \sf\longmapsto D_f=\[1,11\]](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20D_f%3D%5C%5B1%2C11%5C%5D)
So having 1 and 11 as domain we can say the equation is

As it's greater than and equal to the answer can be equal to (=) form.
