Question

Can you solve these questions and explain them for me? Thank you

Answer 1

Step-by-step explanation:

When folding up the box, x will be the height

(30-2x) will be the length

(25-2x) will be the width so

$v(x) = x(30 - 2x)(25 - 2x)$

b. First, we can't have negative length or zero length so x must be Positve.

Set the other binomial equal to 0.

$30 - 2x > 0$

$- 2x > - 30$

$x < 15$

$25 - 2x > 0$

$- 2x > - 25$

$x < 12.5$

So our domain is

(0,12.5), meaning our value of x must be greater than 0 and less than 12.5
