The area of a rectangle is 276.9 m². If the length is 15 m, what is the perimeter of the

valentina_108 [34]

Answer:

$66.92\:\mathrm{m}$

Step-by-step explanation:

The area of a rectangle is given by $l\cdot w$ where $l$ is the length of the rectangle and $w$ is the width of the rectangle. Therefore, based on the information given, we can write the following equation to solve for the width:

$15\cdot w=276.9,\\w=\frac{276.9}{15},\\w=18.46\:\mathrm{m}$ .

The perimeter of a rectangle is given by $p=2w+2l$ . Therefore, the perimeter of the rectangle is:

$2(15)+2(18.46)=\fbox{$66.92\:\mathrm{m}$}$ .

Given the following question:

First expression:

$\begin{gathered} \frac{12x^3-14x^2+16x-8}{3x-2} \\ \text{ Factor the expression:} \\ 12x^3-14x^2+16x-8=2(6x^3-7x^2+8x-4) \\ \frac{2\left(6x^3-7x^2+8x-4\right)}{3x-2} \\ \text{ Factor:} \\ 2\left(6x^3-7x^2+8x-4\right)=(3x-2)(2x^2-x+2) \\ =(3x-2)(2x^2-x+2)=2\left(3x-2\right)\left(2x^2-x+2\right) \\ \frac{2\left(3x-2\right)\left(2x^2-x+2\right)}{3x-2} \\ \text{ Cancel the common factor:} \\ -(3x-2) \\ 4x^2-2x+4 \end{gathered}$

Answer:

10x +6y - 14

Step-by-step explanation:

3x - 2y = 13x + 4y = 14

3x = 13x + 6y = 14

-10x = 6y = 14
