Answer:

Step-by-step explanation:

Numerator = y/ab - ab

= y/ab - ab * ab/ab (LCM = ab)

= (y - a²b²)/ab

Denominator = 1/a - a/b

= 1*b/a*b - a*a/b*a (LCM = ab)

= (b-a²)/ab

(y/ab - ab ) / ( 1/a - 1/b) = (y - a²b²)/ab * ab/ (b-a²)

= (y - a²b²)/ (b-a²)

Triangles are similar ,

Thus :

$\frac{9}{3} = \frac{6}{x} \\$

$3 = \frac{6}{x} \\$

$\frac{6}{x} = 3 \\$

Inverse both sides

$\frac{x}{6} = \frac{1}{3} \\$

Multiply sides by 6

$6 \times \frac{x}{6} = 6 \times \frac{1}{3} \\$

$x = 2 \times 3 \times \frac{1}{3} \\$

$x = 2$

Find the length of the side of rhoumbus whose diagonals are of length 6cm and 8cm.

Artist 52 [7]

Answer:

In a rhombus, the diagonals bisect at right angles. That means half the diagonals form a right angle triangle then we can try the Pythagorean theorem. so -

one side of triangle = 6/2 =3 (half of the diagonal)

other side = 8/2 = 4

a^2 + b^2 = c2

3 ^2 + 4^2 = c^2

9+16 = c^2

c^2=25

c = $\sqrt{25}$ = 5

the hypothenus forms one side of the rhombus and here the hypothenus is 5, so the lenght of a side is 5 !
