Question

enter the missing values in the area model to find $-4(5g + 7.7)$

answer attempt 1 out of 2

according to the model above, $-4(5g + 7.7) = \square$

Explanation:

Step1: Multiply -4 by 5g

$\boldsymbol{-4 \times 5g = -20g}$

Step2: Multiply -4 by 7.7

$\boldsymbol{-4 \times 7.7 = -30.8}$

Step3: Sum the two products

$\boldsymbol{-20g + (-30.8) = -20g - 30.8}$

Answer:

First missing box: $\boldsymbol{-20g}$
Second missing box: $\boldsymbol{-30.8}$
Final expanded form: $\boldsymbol{-20g - 30.8}$
