Actually Welcome to the Concept of the areas,
Area of a rectangle = length * width.
hence, l = 11 and w = 4
hence, 4*11 = 44 square units.
Area = 44 sq. units
A ball is thrown straight up from the top of a tower that is 280 ft high with an initial velocity of 48 ft/s. The height of the
object can be modeled by the equation s ( t ) = -16 t2 + 48 t + 280. Determine the time(s) the ball is lower than the building. Express your answer in interval notation. In two or more sentences, describe your solution method.

We first need to factorize (if possible) the denominators:
we can see that
as 2 and 5 are two numbers whose sum is 7 and product is 10.
Similarly, we can see that
as 2 and 3 are two numbers whose sum is 5 and product is 6.
Thus, the expression is:
.
Now to make the denominators equal, but to also keep them as small as possible, the common denominator must be (p+3)(p+2)(p+5).
Answer: (p+3)(p+2)(p+5).
