Check the picture below.
so we really have 2 equal triangles with 3 rectangles, so let's get the area of each and sum them up.
![\stackrel{\textit{two equal triangles}}{2\left[ \cfrac{1}{2}(8)(6) \right]}~~+~~\stackrel{back}{(6\cdot 4)}~~ +~~\stackrel{bottom}{(8\cdot 4)}~~+~~\stackrel{top}{(10\cdot 4)}\implies 144](https://tex.z-dn.net/?f=%5Cstackrel%7B%5Ctextit%7Btwo%20equal%20triangles%7D%7D%7B2%5Cleft%5B%20%5Ccfrac%7B1%7D%7B2%7D%288%29%286%29%20%5Cright%5D%7D~~%2B~~%5Cstackrel%7Bback%7D%7B%286%5Ccdot%204%29%7D~~%20%2B~~%5Cstackrel%7Bbottom%7D%7B%288%5Ccdot%204%29%7D~~%2B~~%5Cstackrel%7Btop%7D%7B%2810%5Ccdot%204%29%7D%5Cimplies%20144)
Answer:
12
Step-by-step explanation:
Let the number be x
<span>Then According to the equation : </span>
<span>2(X-4)=3(x+5) </span>
<span>2X-8=3X+15 </span>
<span>-23=3X-2X </span>
<span>X=-23</span>
