Factor completely 3x^2− x − 4.

( x + 1 ) ( 3 x − 4 )

Step-by-step explanation:

3x^2− x − 4

Factor − 1 out of − x .

3 x^2 − ( x ) − 4

Rewrite − 1 as 3 plus − 4

3 x^2 + ( 3 − 4 ) x − 4

Apply the distributive property.

3 x^2 + 3 x − 4 x − 4

Group the first two terms and the last two terms.

( 3 x 2 + 3 x ) − 4 x − 4

Factor out the greatest common factor (GCF) from each group.

3 x ( x + 1 ) − 4 ( x + 1 )

Factor the polynomial by factoring out the greatest common factor, x + 1 .

( x + 1 ) ( 3 x − 4 )

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
