Answer:
D is the correct option
Step-by-step explanation:
2x-3/x ÷ 7/x²
Change the division sign into multiplication and the second term will be flipped(denominator will become numerator)
2x-3/x * x²/7
x will be cancelled out by x²
2x-3/1 * x/7
Now multiply 2x-3 by x
2x²-3x/7
Take x as a common:
x(2x-3)/7
Thus the correct option is D....
Given :
Area of rectangle.
To Find :
The dimensions of a rectangle (in m) with area 1,728 m2 whose perimeter is as small as possible.
Solution :
Let, the dimensions of rectangle is x and y.
Area, A = xy.
x = A/y. ....1)
Perimeter, P = 2( x + y )
Putting value of x in above equation, we get :

For minimum P,

SO, it is a square.

Therefore, the dimensions are
.24\sqrt{3}
Hence, this is the required solution.
Answer:
