expressions equivalent? Show your work.

Answer 1

Answer:

Yes they are equivalent, both equations equals $15d+20$

Step-by-step explanation:

We first simplify Olivia's equation

$6d + 8 + 9d + 12$

1. we combine like terms in the equation: $6d + 8 + 9d + 12$

$6d+9d$

$8+12$

$15d+20$

Now we simplify Isabella's

$5(3d + 4)$

1. we do distributive property

$5*3d$

$5*4$

$15d+20$
