<em>So to solve for a variable, you have to isolate that variable onto one side.</em>

Firstly, multiply both sides by j: $h-4=kj$

Next, divide both sides by k and <u>your answer will be: $\frac{h-4}{k}=j$ </u>

Firstly, add g on both sides: $\frac{x}{5}=a+g$

Next, multiply both sides by 5 and <u>your answer will be: $x=5(a+g)$ </u>

Firstly, subtract 5p on both sides: $9c=-4p$

Next, divide both sides by 9 and <u>your answer will be $c=-\frac{4}{9}p$ </u>

You are planning to make an open rectangular box from aa 4141-in.-by-8181-in. piece of cardboard by cutting congruent squares

marissa [1.9K]

Answer:

13058.83 cubic inches

Step-by-step explanation:

Given that a rectangular box is having dimensions as 41x81 inches.

Let x be the side of square cut from all the four corners.

The open box made would have height as x and length 41-2x with width 81-2x

Volume =

$V(x) = x(41-2x)(81-2x)\\V(x) =x(3321-244x+4x^2)\\V(x) = 3321x-244x^2+4x^3\\V'(x) = 3321-488x+12x^2\\V"(x) = -488+24x\\$

Equate first derivative to 0

We get applicable root as x = 8.642

Max volume = 13058.83 cubic inches
