Answer:
us set up the following variables:

l
Length of Rectangle (cm)
w
Width of Rectangle (cm)
A
Area of Rectangle (
c
m
2
)
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
t
)
(
w
)
∴
d
A
d
t
=
3
l
+
8
w
So when
l
=
20
and
w
=
10
⇒
d
A
d
t
=
3
⋅
20
+
8
⋅
10
∴
d
A
d
t
=
60
+
80
∴
d
A
d
t
=
140

Answer:
8X+.07Y=W
Step-by-step explanation:
x is your hours and y is your sales
he makes 8 an hour, hence 8X or 8 x X
7 percent written as a decimal is .07 and his commission for sales, so .07Y
add them together and you get your equation:
8X+.07Y=W
Hey there!
3,562: 1, 2, 13, 26, 137, 274, 1781, 3562
15b: 1, 3, 5, 15, b
5b: 1, 5, b
☆ Not all of the terms have b in it so we know We can't have that as an answer. Only two of the numbers have b in it
The one you see most common would be the biggest/greatest common factor would be
