Answer:
1372.16
Step-by-step explanation:
If I am not mistaken, the answer is just 1.34*1024, which is 1372.16. Also, I assume that "moles" mean molecules.
(b)
A polynomial has the form

+ ....
the only expression fitting this description is : x² + 2x + 7
Answer:
20 ft by 60 ft
Step-by-step explanation:
"What should the dimensions of the garden be to maximize this area?"
If y is the length of the garden, parallel to the stream, and x is the width of the garden, then the amount of fencing is:
120 = 3x + y
And the area is:
A = xy
Use substitution:
A = x (120 − 3x)
A = -3x² + 120x
This is a downward facing parabola. The maximum is at the vertex, which we can find using x = -b/(2a).
x = -120 / (2 · -3)
x = 20
When x = 20, y = 60. So the garden should be 20 ft by 60 ft.

I am assuming that you mean (4,−9) and (8, -3).
Hope this helps.
Answer:
i cant really see it but i think the answer is 5
