Find the perimeter of a rectangle L= 2x^2+3x+1 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 $P(x) = (4x^{2} + 8x + 8)$

The graph of y^2=x^2 is symmetric with respect to which axis? a. x-axis c. both b. y-axis d. neither

PtichkaEL [24]

Answer:

c. both

Step-by-step explanation:

Given equation is $y^2=x^2$

Now we need to check if the graph of $y^2=x^2$ is symmetric with respect to which axis?

a. x-axis c. both b. y-axis d. neither

We know that if f(-x) reflect the graph about y-axis

so let's change x by -x into given function to see if that equation remains unchanged or not

$y^2=(-x)^2$

$y^2=x^2$

That is same as previous equation.

Hence given graph is symmetric about y-axis.

We know that if -f(x) reflect the graph about x-axis

so let's change y by -y into given function to see if that equation remains unchanged or not

$(-y)^2=x^2$

$y^2=x^2$

That is same as previous equation.

Hence given graph is symmetric about x-axis.

So the correct choice is c. both
