The number 36 is really 36.000000... with infinite zeroes
so to divide by tan move the decimal one place to the left
<span>so 36/ 10= 3.6 </span>
The expression for the area in terms of the width is:
A
=
w
2
+
7
w
When
w
=
12
, the area is
228
units.
Explanation:
We know that the formula for the area of a rectangle is:
Area = length x width
A
=
l
w
In this specific case, though, we are told that the length is
7
units greater than the width:
l
=
w
+
7
We can substitute this value for
l
into our area formula, and then there will be only one variable on the right-hand side:
A
=
l
w
=
(
w
+
7
)
w
=
w
2
+
7
w
This expression is the answer to the final sentence in the question, asking us to write an expression for
A
in terms only of
w
.
Now we can use our expression to find the area in the situation where
w
=
12
:
A
=
w
2
+
7
w
=
12

=

Since the 2 lines have the same slope, then the lines are parallel and never intersect. Thus there is no solution to the system of equations

4 cups = 1 quart
4 quarts = 1 gallon
- 8 cups x 7 days = 56 cups
56 cups = 3.5 gallons

16 ounces = 1 lb
Colleen started off with 70 ounces after she takes some off she has 56 so,
70 - 56 = 14(ounces she took off)
