jesse writes an expression that is equivalent to 10 - 2d - 4 + 12d. is jesse correct? yes. jesse is correct. no. he makes a mistake when he writes the expression as a sum in step 1. no. he makes a mistake when he groups the like terms in step 2. no. he makes a mistake when he combines the like terms in step 3. 10 - 2d - 4 + 12d = 10+( - 2d)+( - 4)+12d step 1 =10+( - 4)+(2d + 12d) step 2 = 6 + 14d step 3

Answer

Explanation:

Step1: Rewrite as sum

$10 - 2d-4 + 12d=10+( - 2d)+(-4)+12d$

Step2: Group like - terms

$=[10+( - 4)]+(-2d + 12d)$

Step3: Combine like - terms

$=6 + 10d$

The original work got $6 + 14d$ in Step 3, which is wrong when combining the $d$ terms.

Answer:

No. He makes a mistake when he combines the like terms in Step 3.
