Martin is using unit cubes to build a tower in the shape of a rectangular prism. A decripion of the tower is listed the bottom l

leva [86]

Answer:

Volume of the completes tower = 160 units³

Step-by-step explanation:

Martin is using unit cubes to build a tower in the shape of rectangular prism.

Bottom layer of the prism is in the square shape.

Since number of unit cubes used in the bottom layer = 16

So, one side of the square base will measure = √16 = 4 units

Therefore, Length = width = 4 units

On this base, additional layers added on the top = 9

Therefore, height of the tower = (9 + 1) = 10 units (each layer having 16 cubes)

Volume of the tower = Volume of the rectangular prism

= Length × width × height

= 4×4×10

= 160 cubic units.

Volume of the completed tower will be 160 cubic units.

Which number is rational -3 1/2, sqrt 5, pi, 9.23157...

PIT_PIT [208]

-3 1/2 is rational because the decimal ends at -3.5. It is not sqrt(5) because the decimal never ends and the same follows for pi and 9.23157.

The polynomial p ( x ) = x 3 − 7 x − 6 p(x)=x 3 −7x−6p, left parenthesis, x, right parenthesis, equals, x, cubed, minus, 7, x, m

avanturin [10]

Answer:

$p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)$

Step-by-step explanation:

Given that polynomial:

$p(x)=x^3-7x-6$

Known factor: $(x+1)$

To find:

Equation of the polynomial as the product of linear factors.

Solution:

The degree of polynomial is 3, and when we divide it by a linear equation, the result will be a quadratic. That quadratic will have 2 solutions.

We can solve the quadratic in two linear factors and as a result we will have the answer.

First of all, we need to divide the polynomial $p(x)$ with the given factor $(x+1)$ to find the other factors.

$\dfrac{x^3-7x-6}{x+1} = x^2-x-6$

Solving the quadratic:

$x^2-x-6 = x^2-3x+2x-6\\\Rightarrow x(x-3)+2(x-3)\\\Rightarrow (x+2)(x-3)$

So, the answer is:

$p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)$
