The solution is not unique, but given that
, by the Pythagorean identity we have two solutions for
:
Then from this, we have two corresponding solutions for
. By definition,
and so we can have, in the case of
.
or
in the case that
.
Formula- Area = L • W
So...
Length = 18 + 3
Width = 18 + 3
Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.
Length = 21
Width = 21
Now you’re gonna want to multiply 21 by itself.
21 • 21 = 21 + 420 = ?
Which leaves you with the final sum of...
Area = 441 yds.

Answer:
- 63 in the class
- (C+B)P' = 25
- (C+B+P)' = 18
Step-by-step explanation:
The number of students in the class is the total of all numbers on the diagram:
9 +5 +11 +6 +3 +4 +7 +18 = 63 . . . students in the 2015 senior class
__
Students taking Chem or Biology, but not Physics are those in the colored area, excluding those in the green:
9 +5 +11 = 25 science students not taking Physics
__
Students not taking science are those outside the colored areas:
18 students are not taking science
The correct answer is y-axis, x-axis, y-axis, x-axis.
X/3=1351/7
cross multiply
7x=4053
divide by seven on both sides
x=579
