Given that r and s are both irrational numbers, determine which statement is true.

(A)The values of r + s and r · s are sometimes irrational.

(B)The value of r + s is sometimes irrational, and the value of r · s is never irrational.

(C) The values of r + s and r · s are never irrational.

(D) The value of r + s is always irrational, and the value of r · s is sometimes irrational.

(E)The value of r + s is always irrational, and the value of r · s is never irrational.

(F)The values of r + s and r · s are always irrational.

(G)The value of r + s is never irrational, and the value of r · s is always irrational.

(H) The value of r + s is sometimes irrational, and the value of r · s is always irrational.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
