Using the distributive property to find the product (y – 4)(y2 + 4y + 16) results in a polynomial of the form y3 + 4y2 + ay – 4y
Crank

Answer:

The answer to your question is a = 16

Step-by-step explanation:

Polynomial

                  (y - 4) (y² + 4y + 16)

Process

1.- Multiply y by each term of the polynomial

                y(y² + 4y + 16) = y³ + 4y² + 16y

2.- Multiply -4 by each term of the polynomial

                -4(y² + 4y + 16) = -4y² - 16y - 64

3.- Write both results

                y³ + 4y² + 16y - 4y² - 16y - 64

In bold we notice that a = 16

The cube shaped box is 6 inches wide and the rectangular box is 10 inches long 4 inches wide and 4 inches high. How much greater
nasty-shy [4]

Answer:

Formula of the volume for a cube= s^3 (side, length, width, or edge is acceptable for s)

Formula of the volume for a rectangular prism= lwh (length*width*height)

<u><em>= 50 cubic in. more</em></u>

Step-by-step explanation:

cube: 6^3

6x6x6

36x6

216

rectangular prism: 10x4x4

10x16

160

cube - rectangular prism= Difference between cube and rectangular prism

216   -   160                      =  50

<em>*REMEMBER that when dealing with volume the units are cubic (whatever), in this case, its cubic inches(in^3).</em>
