Let O be the intersection of the vertical line through ZX, and the horizontal line through YW.
The coordinates of this point are clearly (5, 2) as it is at the same x-coordinate as X and Z, and y-coordinate as Y and W.
So, YZO is a right triangle. By the Pythagorean theorem:
.
Since all sides of a rhombus are equal, then the perimeter is :
units.
Answer: third choice.

Answer:
c, d and e
Step-by-step explanation:
A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.
Option a:
Here, the exponent of the variable is 1.
So, it is a linear expression.
Option b:
Here, the exponent of the variable is 1.
So, it is a linear expression.
Option c:
Here, the highest exponent of the variable is 2.
So, it is NOT a linear expression.
Option d:
Here, the exponent of the variable is 2.
So, it is NOT a linear expression.
Option e:
Here, sum of exponents of variables is 2.
So, it is NOT a linear expression.
Hence, c, d and e are NOT algebraic expressions.
