Question

use the distributive pro\

1. \\( 3(-4x + 7) \\)

Explanation:

Step1: Apply distributive property

The distributive property is \( a(b + c)=ab+ac \). Here, \( a = 3 \), \( b=-4x \), and \( c = 7 \). So we multiply 3 with each term inside the parentheses:
\( 3\times(-4x)+3\times7 \)

Step2: Calculate each product

Calculate \( 3\times(-4x)=-12x \) and \( 3\times7 = 21 \). Then combine the results:
\( -12x + 21 \)

Answer:

\( -12x + 21 \)
