Answer:
1: 42x + 35
2: -2x-10
3: -2x+10
Step-by-step explanation:
To answer these questions, what we need to do is multiply out the brackets.
You can do this by multiplying the outside number by the terms on the inside.
For example if we do this with the first one:
7 x 6x = 42x
7 x 5 = 35
add them together = 42x + 35.
You use the same technique for 2) and 3).
Hope this helps! Let me know if you have any questions :)
