The length of a rectangle is (2x+1). The width of the rectangle is (x2+2x-1) what equation represents the perimeter of the rectangle?
A) x to the seconds power+x+3
B)2x to the second power+2x+6
C)2x to the second power+8
D) x to the third power+2x to the second power+x+3

The perimeter of the rectangle is . All options are incorrect.

Given:

The length of the rectangle is .

The width of the rectangle is .

To find:

The equation for the perimeter of the rectangle.

Explanation:

Perimeter of a rectangle is:

Where, is length and is width.

Using the above formula the perimeter of the rectangle is;

Therefore, the perimeter of the rectangle is and all options are incorrect.

The formula to find the perimeter of a rectangle is 2*length + 2*width

2(2x+1)+2(x^2+2x-1)

First we want to distribute the 2 through both the length and the width

(4x+2) + (2x^2+4x-2)

After we distributed the 2 through like we did up above, we now want to add them together to find the perimeter.

We want to combine all like terms

2x^2, doesn't combine with anything so we leave it the same

4x+4x=8x, add the coefficients and leave the variable

2-2=0, we just leave that out, don't do anything with it

What we have left is:

2x^2+8x,

Which would be C), if the answer is 2x to the second power+8x,

Hope this helps ;)

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
