Question

I’m confused.. please help me

Answer 1

The answer is 3x^4 + 24x^2 - 6

explanation:

A = l × w

= (3x^2+4x-2)(x^2+6x+3)

=(3x × x) + (4x×6x) + (-2×3)

= 3x^2 + 24x^2 - 6

Answer 2

Answer:

It's $3x^4+22x^3+31x^2-6$

Step-by-step explanation:

Area is L times width

LW=H

and the length is $3x^2+4x-1$ times the width $x^2+6x+3$

basically you multiply yhem togetheer and combine like terms and voila
