+20 Expand. \(2\cdot7b=14b\)
\(2\cdot-6=-12.\)
\(-5\cdot2b=-10b\)
\(-5\cdot-3=15\)
Add up all the terms and get...
\(4b+3\)
+220 To simplify this expression, first expand the four terms(in total) in the parantheses. When expanded, you get 14b - 12 - 10b + 15. Simplify this to get 4b + 3.
The simplified expression is 4b+3.
