Answer:
x = 5
Step-by-step explanation:
3 = x/ 3 + 4
This is same as
3/1 = x/ 3 + 4
Then cross multiply
1(x + 4) = 3× 3
x + 4 = 9
x = 9 - 4
x = 5

l
Length of Rectangle (cm)
w
Width of Rectangle (cm)
A
Area of Rectangle (
c

)
t
Time (s)
We are told that:
d
l
d
t
=
8
cm/s (const), and,
d
w
d
t
=
3
cm/s (const)
The Area of the rectangle is:
A
=
l
w
Differentiating wrt
t
(using the product rule) we get;
d
A
d
t
=
(
l
)
(
d
w
d
t
)
+
(
d
l
d

)
(
w
)
∴
d
A
d
t
=

l

8
w
So when
l
=
20
and
w
=
10
⇒
d

=

⋅

∴
d

∴
