volume of a cube= s^3

1=s^3

s=∛1

s=1

there are 6 sides on a cube. therefore, find the area of one side and multiply it by 6 to find the surface area:

s^2=1^2

     =1

multiply the side by 6 to get 6; hence, 6 is the surface area.

answer: no solution

^someone verify me on that i'm not very intelligent

It the beginning, Rosa is twice as old as Pilar, meaning she's older than Pilar. In 4 years however, Rosa's age would be 2 years less than Pilars age 3 years ago, implying that Rosa is younger than Pilar. That doesn't make sense, referring to the beginning of the problem. Therefore, I found that there was no solution.

ah ok thank you!

yeah, but i was thinking what if there are more solutions that i don't know about?

1. the answer that i agree with is here:

ok thank you !!

so the range is [4, inf) ?

ohh ok thank you!! i kept trying to square root things that i forgot about going the other way around haha

ah thank you ok so q=3 and p=3/2 right?

i don't know if this answer is right.. but here you go:

have you looked at this yet? :)

could you make your question readable? thanks

t=tapes

c=CD's

t+c=8

12t+18c=126

multiply {c+t=8} by -12 and set up your system of equations

-12t-12c=-96

12t+18c=126

6c=30

c=5

t=3

check:

5+3=8 yes :)

12(3)+18(5)=126 also yes :)

therefore c=5, t=3

(6*24)+(8*36)+x=800

144+288+x=800

432+x=800

x=368

me and danne9000 should have the same answer :))
