A. The square of an irrational number \sqrt(11)=\sqrt(11)*\sqrt(11)=\sqrt(11^2)=11, which is a rational number. However, in B, C, and D, the two pair of rational numbers cannot multiply to become a rational number.

Answer: option A.        \sqrt{11} . \sqrt{11}

Justification:

By definition the product of the square root of a number times itself is the same number.

This is:     \sqrt{n} . \sqrt{n} = n


Because:    \sqrt{n} . \sqrt{n} =( \sqrt{n})^2 = n


Therefore, for the case given:   \sqrt{11} . \sqrt{11} = 11

And you have proved that the product of the two irrational numbers, √11, is a ratonal number, 11.

On the other hand, the other products, B, C, and D do not yield to a rational number. The result of the products shown on B, C, and D are irrational.

Which equation represents a line that passes through (-2, 4) and has a slope of 2/5
Ronch [10]

An equation represents a line that passes through (-2, 4) and has a slope of 2/5 is y-4 = 2/5(x+2)

<h3>Equation of a line</h3>

The equation of a line in point-slope form is expressed as;

y-y1 = m(x - x1)

where

m is the slope

(x1, y1) is any pint on the line

Substitute the given parameter

y - 4 = 2/5(x-(-2))

y-4 = 2/5(x+2)

Hence an equation represents a line that passes through (-2, 4) and has a slope of 2/5 is y-4 = 2/5(x+2)
