1 answer:

8 0

Answer:

Step-by-step explanation:

What two number multiply to equal 6*(-12) and add to equal -1? That is -9 and +8.

$6q^2-9q+8q-12$

Now factor by grouping

$(6q^2-9q)+(8q-12)\\3q(2q-3)+4(2q-3)\\(3q+4)(2q-3)$

Answer:

$- 1.2 , - \frac{1}{2} ,0.44,\frac{7}{3}$

Step-by-step explanation:

We want to arrange the following numbers on the number line in order from least to greatest.

The numbers are:

$0.44, \frac{7}{3} , - 1.2, - \frac{1}{ 2}$

Let us convert everything into decimals to get:

$0.44,2. \bar3 , - 1.2, - 0.5$

Rearranging from least to greatest, we have:

$- 1.2 , - 0.5 ,0.44,2. \bar3$
