enter the missing values in the area model to find $-10(2.3b - 2)$
answer attempt 1 out of 2
according to the model above, $-10(2.3b - 2) = \square$

Explanation:

Step1: Multiply -10 by 2.3b

$\boldsymbol{-10 \times 2.3b = -23b}$

Step2: Multiply -10 by -2

$\boldsymbol{-10 \times (-2) = 20}$

Step3: Sum the two products

$\boldsymbol{-23b + 20}$

Answer:

First missing box: $\boldsymbol{-23b}$
Second missing box: $\boldsymbol{20}$
Final simplified expression: $\boldsymbol{-23b + 20}$
