4a + 4b is one possible answer.
Expressions that are equal to ( 5a + b ) include ( 2(2.5a) + b ), ( 5a + 1b ), and ( 10a/2 + b ). Any expression that can be algebraically manipulated to yield ( 5a + b ) is also equal, such as ( 5(a + \frac{b}{5}) ) or ( (4a + a) + b ). Essentially, any combination that maintains the same coefficients for ( a ) and ( b \ will qualify.
a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.
Four equivalent expressions for B plus A are: A plus B B + A A + B The sum of A and B These expressions represent the same mathematical operation, simply rearranged or represented differently.
(a + 2 - b) (a + 2 + b)

5ab-2ab+4a-b+5b = 3ab+4a+4b
a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.
a-b+a-b+2b+a = 4a
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
7a-2b
The expression is: (4a+b)/(2a-5b)
Four equivalent expressions for B plus A are: A plus B B + A A + B The sum of A and B These expressions represent the same mathematical operation, simply rearranged or represented differently.
(ab/b) / (4a/5b) =(ab / b) * (5b / 4a) = (5ab2 / 4ab)= 5 / (4b)
(a + 2 - b) (a + 2 + b)
1/4
It is equal to a^3 + b^3. It can also be expressed as (a + b)*(a^2 - ab + b^2) or (a^6 - b^6)/(a^3 - b^3) or many other expressions.
It is 2a-b simplified
