**Answer:**

The answer is 4x

**Step-by-step explanation:**

**Answer:**

x =5 ±sqrt( 31)

**Step-by-step explanation:**

x² + 10x = 6

b = 10

Take b/2 and square it

(10/2) = 5 5^2 = 25

Add 25 to each side

x² + 10x+25 = 6+25

The left side will be (x+b/2)^2

(x+5)^2 = 31

Take the square root of each side

sqrt((x+5)^2) = ±sqrt( 31)

x+5 = ±sqrt( 31)

Subtract 5 from each side

x+5-5 = -5 ±sqrt( 31)

x =5 ±sqrt( 31)

Answer:

Pat Pet's Palace

Step-by-step explanation:

Price of dog food at Pat Pet's Palace = $3 per pound

Price of dog food at Mark's Mutt Market can be estimated using the graph given.

The graph is a proportional graph, thus, the constant of proportionality between cost and pound = y/x

Using the coordinates of a point on the line, (2.5, 10), constant of proportionality or unit rate = y/x = 10/2.5 = 4.

This means the price of dog food at Mark's Mutt Market is $4 per pound.

Therefore, Milo would pay a lower price per pound for dog food at Pat Pet's Palace.
