Ricardo is building a rectangular wooden box to ship a large item in. he needs the length of the box to be 30 inches longer than the width. he also needs the height of the box to be 5 inches shorter than the width. create an equation to represent the volume of the wooden box in terms of the width. the question wants me to fill in the blank y=_+_x^2-_x. it also asks what the largest width would be.

x³ + 25x² - 150x

Step-by-step explanation:

It is given that,the length of the box to be 30 inches longer than the width. He also needs the height of the box to be 5 inches shorter than the width.

To find the equation to represent volume

Let 'x' be the width of the rectangle

Length = x + 30

Height  = x - 5

Volume of rectangle = Length * width *height

 = (x + 30) * x * (x - 5)

 = x(x + 30)(x - 5)

 = x(x² - 25x -150)

 = x³ + 25x² - 150x

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
