To evaluate the variable expression 3a + 2b, you need specific values for the variables a and b. Once you have those values, you substitute them into the expression and perform the arithmetic operations. For example, if a = 4 and b = 5, then 3(4) + 2(5) = 12 + 10 = 22. This gives you the final value of the expression.
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

(a + 2b)(c + 2d)
2b
The expression "a plus 2b" represents a mathematical equation where "a" is added to double the value of "b." Without specific values for "a" and "b," the expression cannot be simplified further. If you have numerical values for "a" and "b," you can substitute them in to calculate a specific result.
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
