Answer:

4 * 2y + 4 * 1

4(2y + 1)

Distributive property

Step-by-step explanation:

8y + 4

We can factor out a 4 out of both as both are divisible by 4

8y / 4 = 2y

4 / 4 = 1

So 8y + 4 is the same as saying 4 * 2y + 4 * 1

This can be written as 4(2y + 1) which is written using the distributive property

Step-by-step explanation:

If it sold 35% and now there is 280 remaining, that means that they produce 280 x 135%. That is also equal to 280 x 1.35. The equation is equal to 378 remaining. Please give me brainiest if you see this. However, it is ok if not since this is a super late answer plus I didn't use equivalent ratios.
