Here you go, so essentially you have the two numbers, you write the first one, then the less than sign, then X, then the less than or equal to then 9

Answer:

<h3>The area of the given rectangle increasing when l=20cm and w=25 cm by fast is $300cm^2 per s$ </h3>

Step-by-step explanation:

Given that the length of a rectangle is increasing at a rate of 8cm per s and its width is increasing at a rate of 5cm per s.

<h3>To find the how fast is the area of the rectangle increasing when the length is 20 cm and the width is 25 cm:</h3>

Let l be the Length of Rectangle (cm)

Let w be the Width of Rectangle (cm)

Let A be the Area of Rectangle ( $cm^2$ )

Let t be the Time (s)

From the given we can write

cm per s and

cm per s

The formula for Area of the rectangle is:

A=lw square units

Differentiating with respect to t

$\frac{dA}{dt}=(l)(\frac{dw}{dt})+(\frac{dl}{dt})(w)$ ( by using the product rule formula $\frac{d(uv)}{dx}=u(\frac{dv}{dx})+\frac{du}{dx}(v)$ )

$=l(5)+8(w)$

when l=20 and w=25

$=(20)(5)+8(25)$

$=100+200$

$=300$

∴ $\frac{dA}{dx}=300 cm^2 per s$

<h3>∴ the area of the rectangle increasing by fast is $300cm^2 per s$ </h3>

What is 12.08 written as a mixed number

Alika [10]

128 over 10 because this as a fraction is 12 and 8/10 so then times 12 by 10 and you get 120 then add 8 and then you get 128 and put it over 10
