Answer:
The leg measures 14.14 cm
Step-by-step explanation:
The "40 - 40 - 90" special right triangle is an isosceles right triangle because two angles measures the same. (Check the picture)
The legs are the same.
The hypotenuse is:
a × √2
From the question, the length of the hypotenuse is 20 cm.
20 = a × √2
20 ÷ √2 = a
a = 10√2 ≈ 14.14 cm

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.
