400 divided by 5 = 80.
Needs to bag at least 80.
Answer:
Plant 1 is growing faster (choice A)
Step-by-step explanation:
Plug x = 0 into the equation given to find that
y = 3 + 1.5*x = 3 + 1.5*0 = 3
Meaning that at the start, plant 2 is 3 cm tall. Now plug in x = 1
y = 3 + 1.5*x = 3 + 1.5*1 = 4.5
Now plant 2 is 4.5 cm tall. It has grown 1.5 cm since the first measurement. This is the rate of growth. It grows 1.5 cm per day
Compare this to the table and we see that the rate of growth here is 2 cm per day. Each time x increases by 1 in the table, y increases by 2 (eg: from 1.5 to 3.5)
So we see that plant 1 (table) has a larger growth rate compared to plant 2 (equation).

Answer:
28k
Step-by-step explanation:
The perimeter is the sum of the four equal-length sides:
P = 7k +7k +7k +7k
P = k(7 +7 +7 +7)
P = 28k . . . . perimeter of the rhombus
__
Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.
