The area of a rectangular field is 6840 m2. If the width of the field is 72m , what is its length?

IgorLugansk [536]

Answer:

I believe that the answer is 95 meters.

Explanation:

Okay, so to solve this question, you must know the formula to solve for the area of a rectangle/square.

Area of a rectangle/square - l x w

In this question, you can see the the width (72 m) and the area (6840 m²) is already given. What you can do in this situation is to use the opposite operator (division) to solve for the length of the rectangular field.

6840 ÷ 72 = 95

You can always double check to see if the number is correct.

A = l x w

= 72 m x 95 m

= 6840 m²

Really hope this helped. :)

How can I solve it?? ans= 1/2 -1/2x^2

max2010maxim [7]

Answer:

see explanation

Step-by-step explanation:

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Simplify the expression by dividing both terms on the numerator by 2x²

$\frac{x^3+x}{2x^2}$

= $\frac{x^3}{2x^2}$ + $\frac{x}{2x^2}$

= $\frac{1}{2}$ x + $\frac{1}{2}$ $x^{-1}$

Hence differentiating gives

$\frac{1}{2}$ - $\frac{1}{2}$ $x^{-2}$

= $\frac{1}{2}$ - $\frac{1}{2x^2}$
