Answer:

Factors are ( 3x - 1 ) ( x + 1).

Step-by-step explanation:

Given : 3x²+ 2x - 1.

To find : Factor.

Solution : We have given that 3x²+ 2x - 1.

By factoring : 3x²+ 3x -1x - 1.

Taking common 3x in first two terms and -1 from last two terms .

3x( x + 1) -1 (x + 1 ).

On grouping : ( 3x - 1 ) ( x + 1).

Therefore , Factors are ( 3x - 1 ) ( x + 1).

A) $\frac{2 \frac{1}{4}}{ \frac{1}{2}}$
b) $\frac{1}{2}$ • 2 = 1
so $\frac{9}{4}$ • 2 = $\frac{9}{2}$ cups (which is $4 \frac{1}{2}$ )

0.5 is a rational number. True False

velikii [3]

Answer:

true

Step-by-step explanation:

Natural numbers are numbers naturally occurring in nature like 1, 2, 3, 4, 5, 6, 7, 8, 9 . . .

Whole numbers are numbers that are whole, like 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . (the only difference is that there is a 0 included)

Integers include negative and positive numbers like -3, -2, -1, 0, 1, 2, 3, 4 . . .

Rational numbers are include all of the above AND anything that can be turned into a fraction, like fractions and decimals (that have an end) like 0.625, -0.5, 1, 4, 1/4, 6/15, 4.8, etc.

So in this case, yes, 0.5 is a rational number.
