Simplify 8(2n-6)+5(4n+20​

16n-48+20n+100

16n+20n-48+100

36n-52

36n+52

Explanation:

8(2n-6)+5(4n+20​)

distribution process for 8(2n-6)

8·2=  16n

8·(-6)= -48

so it will be 16n-48

distribution process for 5(4n+20​)

5·4n= 20n

5·20= 100

so it will be 20n+100

16n-48+20n+100

simplyfiy

16n+20n=36n

(-48)+100=52

so the answer is 36n+52
