What is the value of the expression 9/14÷(−0.6×2)?

Answers

Answer:

-0.72

Step-by-step explanation:

First we must solve what in parenthesis

-0.6 × 2 = -1.2

Now we must convert [tex]\frac{9}{14}[/tex] to a whole number

To do that simply divide 9 by 14 and that come out as

0.64285714285Round to the tenths

= 0.6

Now multiply

-1.2 × 0.6 = -0.72
9/14÷(−0.6×2)

9/14÷ -1.2

9/14÷ -12/10

9/14 • 10/-12

Answers

The complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)

How to determine the complete factorization?

The expression is given as:

9x² + 3x - 2

Expand the equation

9x² + 3x - 2 = 9x² + 6x - 3x - 2

Factorize the expression

9x² + 3x - 2 = 3x(3x + 2) - 1(3x + 2)

Factor out 3x + 2

9x² + 3x - 2 = (3x - 1)(3x + 2)

Hence, the complete factor of the expression 9x² + 3x - 2 is (3x - 1)(3x + 2)
