Area of the rectangle is given by the polynomial function A(x)=2x^2+18x. If the width of the rectangle is 2x what is the length?

Answers

Answer 1

The length of the rectangle is x + 9 whose width is gives as 2x.

To find the length of the rectangle, we need to express it in terms of the width.

Given:

width of the rectangle is 2x.

The formula for the area of a rectangle is

A = length × width.

As, the polynomial function for the area:

[tex]A(x) = 2x^2 + 18x[/tex]

So, set up the equation:

[tex]2x^2 + 18x =[/tex] [tex]{\text} width x length[/tex]

Substituting the given width = 2x in above equation gives

[tex]2x^2 + 18x = 2x * length[/tex]

Dividing both sides of the equation by 2x:

x + 9 = length

Therefore, the length of the rectangle is x + 9.

Answer: y=12 x =9

Step-by-step explanation:

In a parallelogram the diagonals bisect each other making them equal.

this means 2y + 6 = 30

we can rearrange this as 30 - 6 = 2y

24 = 2y  therefore y = 12

3x - 3 = 24

We can rearrange this as 24 + 3 = 3x

3x = 27

27 / 3 = 9

x = 9

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The question is incomplete.

Please refer to the picture for the complete question.

We have:

A t-shirt increased in price by 1/4. After the increase, it was priced at £65.

Let's suppose the original price was x

(1 + 1/4)x = 65

(1 + 0.25)x = 65

1.25x = 65

x = £52

Thus, the original price was £52 if the t-shirt increased in price by 1/4. After the increase, it was priced at £65.
