Ksenya-84 [330]

Answer:

The answer to your question is 3x + 2

Step-by-step explanation:

Data

Area of the base = 2x² + 3x in²

Volume of the prism = 6x³ + 13x² + 6x in³

Height = ?

Process

1.- Divide the Volume of the prism by the area of the base to get the height

                                       3x   +    2

                     2x² + 3x   6x³  +  13x²  +  6x            

                                      -6x³  -    9x²

                                        0    +   4x²   +  6x

                                              -    2x²   -   6x

                                                     0          0

2.- Conclusion

The height of the rectangular prism is 3x + 2

Which of ghe following is equivalent to (x+4)(3x^2+2x)?
Alexxandr [17]

The given expression is

(x+4)(3x^2 +2x)

And in the second factor, x is common. So on taking x out, we will get

(x+4)(x)(3x+2) = x(x+4)(3x+2)

We can expand it by distributing , that is

(x+4)(3x^2 +2x) = x(3x^2 +2x) +4 (3x^2 +2x)

= 3x^3 +2x^2 + 12x^2 +8x

Combining like terms,

= 3x^3 +14x^2 +8x

And that's the expanded form ., and the given expression can also be written in that way .
