Answer:

11.8 ft

Step-by-step explanation:

mathematically, we know that the area of a square is the square of its side

Let the measure of the side of the patio be p

Mathematically;

p^2 = 140

p = √140

p = 11.83

To the nearest tenth, this is 11.8 ft

There's an infinite number of ways we can rewrite 16 3/4, some of them being:

**Step-by-step explanation:**

**Answer:**

4(x + 1) and 4(x - (-1))

**Step-by-step explanation:**

4(-1 + 1) = 4(0) = 0

(4 (-1) + 5) = -4 +5 = -1

4(-1 - 1) = 4(-2) = -8

(5 - 4(-1)) = 5 + 4 = 9

4(-1 - (-1)) = 4(0) = 0

4 (-1 + (-1)) = 4(-2) = 8

They collected 1500 cans because 1200x.25=300 and then you add 300 to 1200 to get 1500 cans.
