Curly used a shovel to dig his own swimming pool. He figured he needed a pool because digging it was hard work, and he could use
it to cool off after working on it all day. He also planned to build a rectangular concrete deck around the pool that would be 6 feet wide at all points. The pool is rectangular and measures 14 feet by 40 feet. What is the area of the deck?

Answer:
<h2> There is no slope.</h2>Step-by-step explanation:
It means that for a line passing through two points to have the slope, the x-coordinates of these point have to be different.
(-4, 0) and (-4, -10) means x₁ = x₂ = -4, <u>so there is no slope.</u>
{the line is parallel to Y-axis, and has an equation: x=-4}
To simplify the expression we are going to use the distributive property of multiplication: 
.
We can infer from our problem that
, 
, and 
. So lets apply the property to simplify our expression:
We can conclude that the correct answer is <span>-8x3 + 6x2</span>
