Answer:
56
Step-by-step explanation:
First things first we need to make into an understandable equation. Remember that sum means we will be adding 24 and 4. As for doubled that means that 24+4 will be multiplied by 2 so the equation should turn out like this...
[tex]x=2(24+4)[/tex]
Once we have the equation set up we can solve it...
[tex]x=2(24+4)\\x= 48+8\\x=56[/tex]
So the sum of 24 and 4 doubled is 56.
