-4k²(k+6)(k-1). The expression 
can be factored by factor completely to the expression -4k²(k+6)(k-1).
To factor the polynomial by factor completely, we must to use the pattern as follows:
1. Greatest Common Factor
factored into 
2. Factor the trinomial
Melissa's homeroom raised 63% of its goal for the school
fundraiser. Matt's homeroom has raised 48%. Since it is a percentage of their
goal, a situation in which Matts homeroom raised more money that Melissa's
homeroom is when Matts goal is much bigger than melissas goal, so even if
melissas has bigger percentage, matt has more money.
Example
Matts goal is 1000 so 1000*.48 = 480
Melissas goal is 500 so 500*.63 = 315
The diameter of the new rubber ball, to the nearest foot, must be D = 4.0 ft (in the case of the maximum cost).
<h3>
How to find the diameter of the ball?</h3>
Remember that for a sphere of diameter D, the surface area is:
A = 4*pi*(D/2)^2
In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:
$0.02*A = $1
A = $1/$0.02 = 50
So the surface of the ball must be 50 square feet.
Then we solve:
50ft^2 = 4*3.14*(D/2)^2
D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft
