Answer:
For the question below, you will need to find the GCF of 45 and 60. In this instance it is 5, so it will be outside the box. The GCF answers will be inside the parenthesis, which is 7 and 12.
45x + 60 = 5(7x + 12)
In this question you have to multiply 2 with every number inside the parenthesis. So 2 × 10x and 2 × 4.
2(10x+4) = 20x + 8
Hope this helped.
