enter the missing values in the area model to find $-9(9.7z - 8)$
answer attempt 1 out of 2
according to the model above, $-9(9.7z - 8) = \square$

Explanation:

Step1: Multiply -9 by 9.7z

$\boldsymbol{-9 \times 9.7z = -87.3z}$

Step2: Multiply -9 by -8

$\boldsymbol{-9 \times (-8) = 72}$

Step3: Sum the two products

$\boldsymbol{-87.3z + 72}$

Answer:

Area model missing values (left to right): $\boldsymbol{-87.3z}$, $\boldsymbol{72}$
$\boldsymbol{-9(9.7z - 8) = -87.3z + 72}$
