The question is incomplete, here is the complete question:

The perimeter of a rectangle is twice the sum of its length and its width, the perimeter is 40 meters and the length is 2 meters more than twice its width. What is the length?

The length of the rectangle is 14 meters

Step-by-step explanation:

The formula of the perimeter of a rectangle is P = 2(L + W), where

  • L is its length
  • W is its width

Assume that the width of the rectangle is x meters

∵ The width of the rectangle = x meters

∵ Its length is 2 meters more  than twice its width

- Multiply x by 2 and then add to the product 2

∴ The length of the rectangle = 2 x + 2 meters

∵ The formula of the perimeter is P = 2(L + W)

- Substitute L by 2 x + 2 and W by x

∴ P = 2(2 x + 2 + x)

- Add like terms in the bracket

∴ P = 2(3 x + 2)

- Simplify the right hand side

∴ P = 6 x + 4

∵ The perimeter of the rectangle = 40 meters

- Equate P by 40

∴ 6 x + 4 = 40

- Subtract 4 from both sides

∴ 6 x = 36

- Divide both sides by 6

∴ x = 6

∴ The width of the rectangle is 6 meters

∵ The length = 2 x + 2

- Substitute x by 6

∴ The length = 2(6) + 2 = 12 + 2 = 14 meters

The length of the rectangle is 14 meters

Given z=f(x,y),x=x(u,v),y=y(u,v), with x(1,3)=2 and y(1,3)=2, calculate zu(1,3) in terms of some of the values given in the tabl
stich3 [128]

The value of zu(1,3) using the data elements represented on the table of values is q + p

<h3>How to solve the calculus expression?</h3>

The given parameters are:

z = f(x, y)

x = x(u, v)

y = y(u, v)

Where

x(1, 3) = 2 and y(1, 3) = 2

To calculate zu(1,3), we make use of:

z_u(1,3) = f_x(x,y) * x_u(1,3) +  f_y(x,y) * y_u(1,3)

The values x(1, 3) = 2 and y(1, 3) = 2 mean that:

(x,y) = (2,2).

So, we have:

z_u(1,3) = f_x(2,2) * x_u(1,3) +  f_y(2,2) * y_u(1,3)

From the table of values, we have:

f_x(2,2) = q

x_u(1,3) = 1

f_y(2,2) = 1

y_u(1,3) = p

So, the equation becomes

z_u(1,3) = q * 1 +  1 * p

Evaluate the product

z_u(1,3) = q + p

Hence, the value of zu(1,3) is q + p
