Given: Jamal is x years old.

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━

And, his mother is 28 years older than Jamal.

Then, age of Jamal's mother is = (x + 28)

⠀⠀⠀

Jamal's uncle is two times older than Jamal's mother.

⠀⠀⠀

$:\implies\sf Jamal's\: uncle\:age = (Jamal's mother age)\\\\\\ :\implies\sf Jamal's\: uncle\:age = 2(x + 28)\\\\\\ :\implies{\underline{\boxed{\pmb{\frak{\purple{Jamal's\: uncle\:age = 2x + 56}}}}}}\:\bigstar\\\\$

$\therefore\:{\underline{\sf{Hence,\:the\:expression\:that\: represents\: Jamal's\: uncle \:age\:is\: {\pmb{2x + 36}}.}}}$
