2x+3(x-2)-3(x-6) You would first distribute. So: 2x+3x-6-3x+18 Then you would combine like terms, like so: 2x+3x-3x= 2x -6+18= 12 So it'd be: 2x + 12 Which is answer choice A HOPE THIS HELPS!!(:

$2x+3(x-2)-3(x-6) \\ \\ 2x + 3x - 6 - 3x + 18 \ / \ expand \\ \\ (2x + 3x - 3x) - 6 + 18 \ / \ gather \ the \ like \ terms \\ \\ 2x - 6 + 18 \ / \ simplify \\ \\ 2x + 12 \ / \ simplify \\ \\$

The final result is A) 2x + 12.

$f=6cm\\g=8cm$

Why?

The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".

Calculating we have:

$TriangleArea=ABCE-ABCD\\\\TriangleArea=60cm^{2}-48cm^{2}=12cm^{2}$
