Answer:
_____________________________
The problem is that the "volume" of cube is equal to the length of one of its sides, "cubed" ; that is, "V = s³ " .
A cube with with sides that measure 5 cm has the following volume:
_____________________________________________________
" V = (5 cm)³ = 5 * 5 * 5 * cm³ = 125 cm³ " ;
_____________________________________________________
The volume of cube with sides that measure "10 cm"
(which is, in fact, has "side lengths that are TWICE the value of "5 cm" ; gets "cubed" — as opposed to getting multiplied by "2").
_____________________________________________________
So, V = (10 cm)³ = 10 * 10 * 10 * cm³ = 1000 cm³ .
______________________________________________________
When we deal with "volume increases"; we are dealing with "three-dimensional objects", with values of "cubic units" . And in a cube, with all side lengths being equal, an increase in side length will result in an "exponential" increase in volume.
________________________________________________
So; (10 cm)³ ≠ 2* (5 cm)³.

Answer:
-2/-5 = 2/5
Step-by-step explanation:
Answer: i think it is 20.00$
Step-by-step explanation:
L=legnth
w=width
a=area
legnth is 3 more than twice its width
l = 3 + 2 times w
l=3+2w
a=65
a=l times w
subsitute
65=lw
l=3+2w
subsitute
65=(3+2w)(w)
65=3w+2w^2
subtract 65 from both sides
0=2w^2+3w-65
if we can factor then we can do
if zy=0 then assume z and/or y=0 so
to factor in ax^2+bx+c form when a is greater than 1,
aw^2+bw+c
2=a
3=b
-65=c
to factor first find
a times c=z
b=t+y
t times y=z
so
a times c=2 times -65=-130
b=3
factor -130
-130=
-1,130
-2,65
-5,26
-10,13
now add them together and see which ones make 3 or -3 (b)
-1+130=129
-2+65=63
-5+26=21
-10+13=3 match
seperate the middle number like that
3w=-10w+13w
so
2w^2-10w+13w-65=0
group
(2w^2-10w)+(13w-65)=0
factor
(2w)(w-5)+(13)(w-5)=0
reverse distribute ab+ac=a(b+c)
(2w+13)(w-5)=0
set each to zero
2w+13=0
w-5=0
solve
2w+13=0
subtract 13
2w=-13
divide 2
w=-6 and 1/2
impossible since width cannot be negative discard
w-5=0
add 5 to both sides
w=5
subsitute
65=wl
65=5l
divide 5
13=l
width=5 feet
legnth=13 feet
