It is a linear expression with one variable, b. Since it is not an equation it cannot be solved.

They are terms of an algebraic expression that can be simplified to: 2b+2c

3+2b+6 .... is this the question... i think the question will be 3+2b=6 b=1.5

It is an expression that can be simplified to: 3a-2b+c

-7a-7b

(a + 2b)(c + 2d)

2b

a + 7b + 2c

18h+4b-2b

There is no graph because there is no equation - only an expression.

ac + 2ad + 2bc + 4bd = a(c + 2d) + 2b(c + 2d) = (a + 2b)(c + 2d) Now expand to confirm your answer: c(a + 2b) + 2d(a + 2b) = ac + 2bc + 2ad + 4bd ≡ ac + 2ad + 2bc + 4bd
