yarga [219]

Answer:

0.01x = 40

x = 4000

vagabundo [1.1K]
Let x = the length of a side of the square (m).
The area is
A = x²
The perimeter is
P =  4x

The rate of change of P with respect to x is
P'(x) = 4  (independent of x)

When A = 49 m², then x = 7 m.
The rate of P is 4.

Which inequivalnet is equivalent to |x-4|<9
nikklg [1K]

Answer:

something like this?

\left \{ {{x-4  

the top one is valid when x-4 >0

the bottom one is valid when x-4<0

Step-by-step explanation:

absolute value  |x-4|

means that in case x-4 is negative, we will use -(x-4)

if it's positive we use x-4

let's find the solution (where the original inequality is true)

negative case:

-(x-4)<9    -x+4 < 9  -x < 5  x>-5

positive case:

x-4 < 9   x < 13

to satisfy both conditions -5 < x < 13
