9.72 × 10²

Step-by-step explanation:

A number written in standard form is of the form

a × ( where 1 ≤ a < 10 and n is an integer )

We require to write the number between 1 and 10 , that is

9.72 ×

To get the number back to its true value we require to multiply by 100, then

972 = 9.72 × 100 = 9.72 × 10² ← in standard form

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
