Question

URGENT HELP! FAN + METAL
The area of a rectangle is x^3+3x^2+8x+24. If the length is x+ 3, what is the expression for the width?

Answer 1

area = length x width so,
you have the area and the length

Answer 2

the metal part is good

Answer 3

if we do area/length we will get width

Answer 4

can you do that?

Answer 5

can you teach me step by step? that's what i'm having trouble with

Answer 6

yes one moment

Answer 7

thank you (:

Answer 8

I rhink @MathMan77 has this

Answer 9

ok so this is pretty complex and hard to explain hehe, i did a quick google and this website shows simplifying this step by step

Answer 10

this is just volume @MathMan77

Answer 11

look at the factoring section you need to factor this and divide the x+3 out of it

Answer 12

x3-3x2+8x-24

Final result :

(x2 + 8) • (x - 3) this is the important part from the site

Answer 13

that will leave you with the width

Answer 14

the site says how do we get from this x3-3x2+8x-24

Final result :

this (x2 + 8) • (x - 3)

Answer 15

well that may be incorrect a second look revealed that the signs are switched it has some negatives that are positives

Answer 16

but should show you how

Answer 17

first of all area cant be described as x^3 , so you should have told @daisysosa512 that

Answer 18

so now u have to do is divide this

(x2 + 8) • (x - 3) by (x+3)

Answer 19

and u get it

Answer 20

BPD is correct this question dosent really make sense...

Answer 21

sorry i missed that

Answer 22

I think its (x^2 + 8) though

Answer 23

thanks so much! can you help me with this one too? if no then i understand (:
The length of a box is 5 more than the width and the height is 2 less than the width. If thevolume is equal to 150 cubic feet, what are the measurements for each side.

Answer 24

sure daisy, there is an easy way to write these out!

Answer 25

I think @Mathman77 can help
