Is 4d + (15 + 3d) equivalent to (4d + 15) + 3d ?

Sagot :

Answer:

Yes it is

Step-by-step explanation:

4d + 3d = 7d so 7d + 15 would be the expression for both except it would only be 3d + 4d = 7d and 7d + 15 is the same as the first expression that I got from evaluating 4d + (15 + 3d).

Answer:

[tex]\boxed{\boxed{\sf{Yes,~7d+15=7d+15}}}[/tex]

Solution Steps:

______________________________

1.) Solve [tex]\bold{4d+(15+3d)}[/tex]:

  • Combine 4d and 3d: [tex]=7d+15[/tex]

2.) Solve [tex]\bold{(4d+15)+3d}[/tex]:

  • Combine 4d and 3d: [tex]=7d+15[/tex]

3.) Compare:

  • [tex]7d+15=7d+15[/tex]

So your answer [tex]\bold{7d+15=7d+15}[/tex].
