Sam decides to build a square garden. if the area of the garden is 9x2 − 24x + 16 square feet, what is the length of one side of the garden?

(3x + 4) feet

(3x − 4) feet

(4x − 3) feet

(4x + 3) feet

 The correct option is (B)

Step-by-step explanation:  Given that Sam decides to build a square garden whose area is as follows:

We are to find the length of one side of the garden.

Since the given garden is of a square shape, so the length of each side is same.

That is, the area of the garden must be a perfect square trinomial.

We have

Since the area of a square is (length)², so the length of one side of the garden is

Thus, (B) is the correct option.

It is a gain.

Step-by-step explanation:

CLEAR STATEMENT:

Given that the fruit seller buys 10 apples for 45Rs each from wholesale market.

This implies her buys them for 10 × 45Rs = 450Rs.

UNCLEAR STATEMENT:

He packs them in a fruit basket for 40 and sells them each for 20 baskets Rs. 600.

ASSUMING:

What you are trying to say is that he bought baskets for 40Rs, and sold the apples for 600Rs.

Subtracting his expenses from this value, we have

600Rs - 450Rs - 40Rs = 110Rs

Since this amount is positive, we conclude that it is a gain of 110Rs.
