Shapes? We need to know how they look like in order to solve
I am not familiar with "brighten" but this is how you can expand and use the distributive property:
7(256)
= 7(200 + 50 + 6)
= 7(200) + 7(50) + 7(6)
= 1400 + 350 + 30
= 1780
There are 10 seeds for each flower pot. There are 30 flower pots. For this question you have to multiply.
30×10=300
Andre walks for 16 minutes. 80% of 10 is 8 and times that by 2 is 16 so 16 minutes.
