Hey there! 
All we need to do is multiply the unit price of the pencil ($.35) by how many pencils she wants to buy (4)
$.35 x 4 = $1.40
Therefore, she will pay $1.40 for 4 pencils
Hope this helps you!
God bless ❤️

ΔACD is similar to ΔBCD by AA similarity theorem
AD/AC = BD/BC
x/5 = 4.2/6
6x = 21
x = 3.5
Hope this helps! ;)

6x-3
You have to put f(x) into g(x) to find the answer, so you rewrite it like this: 3(2x-1)
