in log minus means divide
log 6 - log 3 = log (6÷3)
log 6 - log 3 = log 2
Answer:
Erich planted 7 seeds ...
he had to remove 17 plants ....
he expected to have less or equal 46 plants ...
Step-by-step explanation:
Look at keywords like remove ~ => which indicates that something is being subtracted
Since x represents seed packets, and the amount he planted is a number multiplied by x, we can deduce he planted 7 seeds ( 7 * x)

Answer:
y = -2x^2(x - 3)
Step-by-step explanation:
<em><u>Preliminary Remark</u></em>
If a cubic is tangent to the x axis at 0,0
Then the equation must be related to y = a*x^2(x - h)
<em><u>(3,0)</u></em>
If the cubic goes through the point (3,0), then the equation will become
0 = a*3^2(3 - h)
0 = 9a (3 - h)
0 = 27a - 9ah
from which h = 3
<em><u>From the second point, we get</u></em>
4 = ax^2(x - 3)
4 = a(1)^2(1 - 3)
4 = a(-2)
a = 4 / - 2
a = -2
<em><u>Answer</u></em>
y = -2x^2(x - 3)
The GCF would be 14a, because 14a x 1 = 14a, and 14a x 2b = 28ab.
