Question

use the area model to multiply 5(11f + 9). first, find the partial products. 11f 9 5 now, write the product. 5(11f + 9) =

Explanation:

Step1: Find first partial product

Multiply 5 and \(11f\).
\(5\times11f = 55f\)

Step2: Find second partial product

Multiply 5 and 9.
\(5\times9 = 45\)

Step3: Add partial products

Add \(55f\) and 45.
\(55f + 45\)

Answer:

First partial product: \(55f\), Second partial product: \(45\)
\(5(11f + 9) = 55f + 45\)
