Use the Distributive Property to simplify the following expression. a: 4(x+2) b; -5(9+x) c: 7(x-3)

ExtremeBDS [4]

<h3>hello!</h3>

=======================================================

The Distributive Property states the following:-

$\longrightarrow\sf{a(b+c)=ab+ac$

Where

$\longrightarrow\sf{a,~b,~and~c~can~be~either~constants~or~variables}$

Now, let's use this property to simplify our expressions.

The first one is

$\bigstar{\underline{\boxed{{4(x+2)}}}$

Simplify by distributing 4:-

$\longrightarrow\sf{4~times~x~+4~times~2}$

Add the products:-

$\longrightarrow\sf{4x+8}$

$\rule{250}{2}$

Solve the next one:-

$\bigstar{\underline{\boxed{\sf{-5(9+x)}}}$

Distribute -5 & add the products:-

$\longrightarrow\sf{-45-5x}$

$\rule{250}{2}$

Solve the last one:-

$\bigstar{\underline{\boxed{7(x-3)}}$

Distribute 7:-

$\longrightarrow\sf{7x-21}$

======================================================

Hope everything is clear; if you need any more explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)
