Find the perimeter of a rectangle <br> L= 2x^2+3x+1<br> W= x+3

ahrayia [7]

Answer:

The perimeter of the rectangle is $P(x) = (4x^{2} + 8x + 8)$

Step-by-step explanation:

Length of the rectangle = $2x^{2} +3x + 1$

Width of the rectangle = x + 3

The Perimeter of the Rectangle = 2 (Length + Width)

So, here the perimeter = $2((2x^{2} + 3x +1 )+(x+3)) = 2 (2x^{2} + 3x + 1 + x +3)\\= 2(2x^{2} + 4x+4) = 4x^{2} + 8x + 8$

Hence,the perimeter of the rectangle is $P(x) = (4x^{2} + 8x + 8)$

Equations with variables on both sides that make the answer x=9

nikklg [1K]

Answer:

$6x-3=2x+33$

Step-by-step explanation:

Apply creative thinking and come up with an equation where the final answer is x=9.

This might give a representation of how to do it algebraically:

$x=9\\4*x=4*9\\4x=36\\4x+2x=36+2x\\6x=2x+36\\6x-3=2x+36-3\\6x-3=2x+33$
