Answer:

x = -5/7 or x = 2

Step-by-step explanation:

7x² - 9x - 10 = 0

Factor the left side of the equation.

(7x + 5) (x - 2) = 0

Set the factors equal to 0.

7x + 5 =0

7x = -5

x = -5/7

x - 2 = 0

x = 2

Answer:

In the given expression x:6 :: 3:9 , x = 2

Step-by-step explanation:

Here, the given expression is:

x:6 :: 3:9

or, x : 6 = 3 :9

So, by the RATIO OF PROPORTIONALITY:

$\frac{x}{6} = \frac{3}{9}\\\implies x = \frac{3}{9} \times 6 = 2$

or, x = 2

Hence, in the given expression x:6 :: 3:9 , x = 2
