The sum of cubes is given as:
a³ + b³ = (a + b)(a² - ab + b²)
Example for the sum of cubes:
64x³+y³ ⇒ This is the sum of cubes because each term; 64, x³, and y³ are cube numbers
By writing each term as an expression of cube numbers, we have:
(4x)³ + (y)³ ⇒ 64 is 4³
Use the factorization of the sum of cubes, we have:
(4x + y) ( (4x)²- 4xy + y²)
(4x + y) (16x² - 4xy + y²)
--------------------------------------------------------------------------------------------------------------
The difference of cubes can be factorized as:
(x³ - y³) = (x - y)(x² + xy + y²)
Example
(125x³ - 8y³) = (5x - 2y) ((5x)² + (5x)(2y) + (2y)²)
= (5x - 2y) (25x² + 10xy + 4y²)
Answer:
They are important becasue that decides how much money that you would pay on top of the borrowed ammount.
Step-by-step explanation:
To start, I had similar questions and I know that it takes 3 cones to fill a cylinder.
And as for the volumes:
V of a cylinder= V=π r<span>2 h (pi x radius squared x height)
Volume of a cone= V=</span><span>π r2 h/3 (pi x radius squared x height divided by 3)</span>
A 40 x 110 rectangle has an area of 4400 sq. ft.
The horse has a 14 ft lead. That makes 14 ft. the radius that the horse can cover.
The formula for the area of a circle is r^2 * PI ( radius squared * 3.14 ).
So the horse can't get to 4400 - ( 14 * 14 * 3.14 ) sq. ft.
