Question

If a cube has a surface area of 6x^2+60+150 what is the length of a side?

Answer 1

6(x^2 +10x+25)

- i think you have missed one x there next 60 ,yes ?

Answer 2

yes I did, thanks after 60

Answer 3

ok

- than 6(x^2 +10x +25) =6(x+5)^2
-so can you continue it ?

Answer 4

- so a cube how many side has ?

Answer 5

x+5

Answer 6

answer me the question please

Answer 7

The question is Find the length of a side?

Answer 8

yes but i have wrote to you from how many sides you will get the surface area of a cube ?

Answer 9

can tel me ?

Answer 10

okay, thanks!

Answer 11

what ? not is ended again

Answer 12

so lateral there are 4 sides and one down and one up so this is total 6
yes ?

Answer 13

than from your equation we have got 6(x+5)^2

Answer 14

- so if 6*(x+5^2 is the surface area of cube so than from this result that one side has area of (x+5)^2
- yes ?

Answer 15

- so but you know that area of a square - because the side of a cube is a form of square
- so area of a square is equal side time side what is side squared
- yes ?

Answer 16

Thank you so much for helping me!

Answer 17

- so than (x+5)^2 will be area of a side than from this resulted that one side will be x+5
- so than x=5 - because one lenght not can be never negativ

Answer 18

hope so much that was understandably sure right

Answer 19

ok ?

Answer 20

yes, it was was! thanks again!
