How do you use distributive property when simplifying the following?

7(3f + 6)
4(9 - 2f)
5(8 - f)

you can just give the answers in order if you want

Hello there!

The Distributive Property allows us to multiply any number/variable outside of the parenthesis by all inside numbers/variables within the parenthesis.

For example;

2(3 + 4)
"2" is our outside number.
"3" and "4" are our inside numbers.
Multiple our outside number by all inside numbers.
2(3) + 2(4)
6 + 8
14.

This is how the Distributive Property works.

Now, let's answer our questions doing this.

#1.)
7(3f + 6)
7(3f) + 7(6)
21f + 42 -- This is your simplified expression for (#1.)

#2.) 
4(9 - 2f)
4(9) + 4(-2f)
36 - 8f -- This is your simplified expression for (#2.)

#3.)
5(8 - f)
5(8) + 5(f)
40 + 5f -- This is your simplified expression for (#3.)

I hope this helps!

Idon't know the answer

c) 6

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
