<h3>

**Answer:**</h3>

(a) $0.80

(b) 1.25 m

<h3>

**Step-by-step explanation:**</h3>

**(a)** Put 1 where L is, and evaluate the equation.

... p = 0.8·1 = 0.8

**The cost for 1 meter of rope is $0.80.**

**(b)** Put 1 where p is and solve for L.

... 1 = 0.8L

... 1/0.8 = L = 1.25

**The length of rope that costs $1 is 1.25 meters.**

**Answer:**

Nope!

**Step-by-step explanation:**

It's linear, because it has a continuous pattern. Look!

x values: 6, 7, 8, 9

y values: 4, 2, 0, -2

X values: We add 1 each time

Y values: We subtract 2 each time

I hope it helps!

Answer:

Andy is incorrect

Step-by-step explanation:

[See attachment for complete question]

Andy is incorrect because of the following.

Filling the empty boxes with any real numbers does not guarantee that the expression will be a polynomial.

For instance, if the expression is completed as thus:

(5x⁴ + 4x³)(4x^(2.7981) - 6) = A

This expression is not a polynomial because all powers of x must be non negative and it must be an integer.

So, Andy's statement is incorrect
