Convert this mixed number to an improper fraction. 2 2/3
kotykmax [81]

Answer:

8/3

Step-by-step explanation:

Take the whole number and multiply it by the denominator. 2 * 3 = 6

Then add that to the numerator. 6 + 2 = 8

8 is your new numerator and 3 stays as the denominator.

Hope this helps!

The length of a rectangle is I m more than twice the width, and the area of the rectangle is 28 m. Find the dimensions of the re
Oksanka [162]

Answer:

width = 3.5 feet        length = 8 feet.

Step-by-step explanation:

 W=x

L=2x+1

Area=(2x+1)x=28

2x^2+x=28

2x^2+x-28=0

 (2x-7)(x+4)=0

x=3.5,-4.  It should be a positive number so W=3.5

2x+1=8          2x3.5=7     7+1 = 8    L=8

That area is 28 ft^2

width is 3.5 feet and length is 8 feet.

Given the polynomial 2x3 18x2 − 18x − 162, what is the value of the constant 'k' in the factored form? 2x3 18x2 − 18x − 162 = 2(
oee [108]

The value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.

<h3>What is polynomial equation?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

The given polynomial equation in the problem is,

2x^3 +18x^2 - 18x - 162

The factor of the polynomial equation are given as,

2(x+ k)(x - k)(x +9)

First find out the factors to compare and find the value of k.The above equation has the unknown variable x and the highest power of this unknown variable is 3.

Take out the highest common factor 2, which can divide each term of the above equation (2, 18, -18, -162). Thus,

2(x+ k)(x - k)(x +9)=2(x^3 +9x^2 - 9x - 81)

Take out the highest common factor to make the groups as,

2(x+ k)(x - k)(x +9)=2(x^2( x+9) - 9(x + 9))\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 9)\\2(x+ k)(x - k)(x +9)=2( x+9) (x^2 - 3^2)

Use the property of difference of the square for the (x²-3²) term as,

2(x+ k)(x - k)(x +9)=2( x+9) (x+3)(x-3)\\2(x+ k)(x - k)(x +9)=2 (x+3)(x-3)( x+9)

On comparing the two equation, we get the value of k as 3. Thus, the value of the constant 'k' in the factored form factorization the provided polynomial equation is 3.
