Among all pairs of numbers whose difference is 14 find a pair whose product is as small as possible
zvonat [6]

The pair two numbers whose difference is 14 and the product is as small as possible (i.e. -49) are (-7,7)

<h3>What are word problems?</h3>

In mathematical concepts, word problems involve a crucial understanding of the problem and knowing which mathematical method and arithmetic operations are best suited to solving the problem.

If we assume that the smaller number should be = a and the larger number = a + 14.

Thus, their product (X) can be expressed as:

= a(a+14)

= a² + 14a

The smallest possible value implies the minimum value, i.e.

\mathbf{\dfrac{dX}{da} = 2a + 14}

Thus,

2a + 14 = 0

a = - 14/2

a = -7

Therefore, we can conclude that the pair of two numbers whose difference is 14 and the product is as small as possible (i.e. -49) is (-7,7).

What is the denominator of the simplified expression? 2 n
Shtirlitz [24]

The expression \frac{2n}{6n + 4} * \frac{3n + 2}{3n - 2} is a product expression

The denominator of the simplified fraction is 3n -2

<h3>How to determine the denominator?</h3>

The expression is given as;

\frac{2n}{6n + 4} * \frac{3n + 2}{3n - 2}

Divide the first fraction by 2/2

\frac{n}{3n + 2} * \frac{3n + 2}{3n - 2}\\

Evaluate the above product

\frac{n}{3n - 2}

The above fraction is a simplified fraction of \frac{2n}{6n + 4} * \frac{3n + 2}{3n - 2}, and the denominator is 3n - 2

Hence, the denominator of the simplified fraction is 3n -2
