Answer:
4+24u
Step-by-step explanation:
Step 1 Write it out
the expression written out is 4 times (1+6u)
Step 2 distribute
Now you distribute
4(1+6u)
4 times 1 is 1
then its 4 times 6u and you get 24u
so your answer is 4+24u and you cant add these two because the 4 doesn't has the same exact variable a the 24 has.
