Answer:
15x+35
Step-by-step explanation:
[tex](3x + 7)5[/tex]
Use 5 to open the bracket
[tex]3x \times 5 = 15x \\ 7 \times 5 = 35[/tex]
[tex]15x + 35[/tex]
3x+35
the ( is a times, you times 7 by 5 and get 35. there is no other number that has a x with it so it stays by itself. You can only do something with the x number if there is another x number.
