Answer:
he expression is undefined where the denominator equals 
0
, the argument of an even indexed radical is less than 
0
, or the argument of a logarithm is less than or equal to 
0
.
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Answer:
A
Step-by-step:
a^2+ b^2 = c^2
if we try A
6^2+8^2 = 10^2 => 64+36  = 100 
 
        
             
        
        
        
Answer: on the number line put -1.50 (1 and a half (1 1/2))
Step-by-step explanation:
$1.50 more than his account is $200. 
the balance should be $-1.50
on the number line put -1.50
 
        
             
        
        
        
Answer:
Therefore  the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Step-by-step explanation:
Pythagorean Theorem: According to this theorem the result obtained by  squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.
Hypotenuse = h
Altitude = l
Base = b
l²+b²=h²
Here 6²=36
9²=81
12²=144
15²=225
From the above it is clear that
81+144=225
⇒9²+12²=15²
Therefore  the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
