Question

PART ONE: Your friend comes up with a design for the perfect garden and says to create it you need an area of 35 square feet. if this is your ideal garden, what would be the measurements of your width and length. PART TWO: during the winter months, MR Dugan assigns another set of students to design a rectangular tent to cover your garden. the volume of their tent was represented by 2x^2-5x^2+3x. the garden still had the original length and width from the previous example, what was the measure of height in terms of x

Answer 1

height = Volume/(lw)

Answer 2

you have to use l and w from part (a)

Answer 3

If you say so, as I didnt do part (a)

Answer 4

well i know you have to do w^2= 35 but is that a quadratic equation?

Answer 5

for part one

Answer 6

you said that you only need a hand with part (b). II stopped helping others to help you with part (b). I cant do part (a) now.

Answer 7

someone questioned my part a but i really need help with part b

Answer 8

Ok.. I will see this problem in 2 min. Just hang on.

Answer 9

ok thank youu!!

Answer 10

OK. I'm back. Let me do both parts.

Answer 11

great! thank youu

Answer 12

In part (a) ...if the area is 35 square feet, the length could be 7 ft and the width could be 5 ft.

Answer 13

agree? becuase 7 ft x 5 ft = 35 square feet

Answer 14

to solve the problem my teacher said you need to use a quadratic equation

Answer 15

Forgive me, but if you read the problem for part(a), it asks you to find a length and width so that the area is 35 square feet. So I chose length to be 7 feet and width to be 5 feet. I don't know what your teacher is referring to. I'm answering the part(a) as posted above. No need for any quadratic equation. It asks for an ideal length and width so that the area is 35 sq ft. I can choose whatever numbers I want, and 7 and 5 are nice numbers.

Answer 16

ok i understand

Answer 17

Take a moment and read part (a). It allows me to choose ideal length and width.

Answer 18

yes, ok i get it noww

Answer 19

it makes sense

Answer 20

So, honestly, I dont begin to understand why your teacher brings up quadratic equation. Unless the teacher was talking about a different problem.

Answer 21

For part (b). You want to find the height of the tent, given the volume, and to use length and width from part(a).

Answer 22

So, as I wrote earlier, Volume = length x width x height

OR V = lwh

we want h, the height. So we divide both sides of the equation by lw.

so the height, h = v/(lw)

so h = (2x^2 - 5x^2 + 3x)/35

I believe there's an error in the volume...because the volume wouldnt have 2x^2 - 5x^2...it would have an x^3 ...but above is the final answer for the height....assuming the volume was typed correctly.

Answer 23

@santashelper Makes sense?

Answer 24

Just make sure that the entire question was typed correctly. I answered the question purely based on what was typed in this post above.

Answer 25

i copied and pasted the question

Answer 26

thats cool; but the volume given is kinda weird volume.

Answer 27

I believe that there is an error in the book itself; they probably meant to put an x^3 or something with an x^3.

Finally, I dont really like this question, as part(b) serves no purpose in giving the volume algebraically, as it doesn't ask the student to do anything with that volume expression.

Answer 28

thank you for your time and help!!!

Answer 29

No proble. Welcome. And ask your teacher about that weird volume...I've never seen a volume expressed with x^2 twice in one expression. Take care and good night.
