Scorpion4ik [409]

Step-by-step explanation:

Hey, there!!

5(R+2)-6.

Fistly multiply (R+2) by 5.

=5R + 10 - 6

Subtract 6 from 10.

= 5R +4.

Therefore, 5R + 4 is correct answer.

{ While simplifying the expression if there is multiplication or divide do it first and then add or or subtract like terms to get the simplified form of the expressions. }
