Answer:

It is impossible to know the solution of this expression unless you know how much a is worth or some information on the other side of the equation. If you don't know what I mean then I'll explain it a bit more. An equation is 2 expressions that are equal to each other but here I don't know anything about the other side of the equation. For example, an equation like this: 3a - 15= 6 is solvable because I know enough information to solve this.

3a - 15 + 15= 6 + 15

3a = 21

Therefore I can now find out what the answer is but your equation does not have enough information for it to be solved.

Suzanne says the two expressions 2(3a – 2) + 4a and 2(5a – 2) are equivalent? Is she correct? Explain why or why not?

pashok25 [27]

Answer:

Suzanne is incorrect.

Step-by-step explanation:

To figure out if the two equations are equivalent, we can simplify each one of them.

Simplifying the first equation, we get:

$2(3a-2)\\6a-4\\$

Simplifying the second equation, we get:

$2(5a-2)\\10a-4$

Now that both equations are simplified, we can see that the equations are not equivalent. Suzanne is incorrect.
