Answer:
D
Step-by-step explanation:
Whole numbers are the basic counting numbers: 
Integers are whole numbers and negative numbers: 
Rational numbers are all fractions  where m is an integer and n is a natural number.
 where m is an integer and n is a natural number.
Irrational numbers are all real numbers that are not rational.
Number  is irrational number (it is not counting number, so it is not whole number, not integer number), it cannot be represented as a fraction, so it is not rational number, thus this number is irrational number.
 is irrational number (it is not counting number, so it is not whole number, not integer number), it cannot be represented as a fraction, so it is not rational number, thus this number is irrational number.
The product of integer number -2 by irrational number  is irrational number
 is irrational number 
Correct option - option D
 
        
                    
             
        
        
        
It is 11 33/40. 11 being the whole number and 33/40 the fraction
        
             
        
        
        
Answer:
f(x) = (x-2) (x+10)
Step-by-step explanation:
f(x)=x^2+8x-20
Factor the right hand side
What 2 numbers multiply to -20 and add to 8
-2 * 10 = -20
-2 + 10 = 8
f(x) = (x-2) (x+10)
Then we can use the zero product property to help us to find the zero's
 
        
                    
             
        
        
        
Answer:
4% of 175,000 is 7,000
7,000x 5=35,000
175,000-42,000 equals 140,000 the value of the house
 
        
             
        
        
        
Answer:
$200 : $150
Step-by-step explanation:
Sum the parts of the ratio, 4 + 3 = 7 parts
Divide the total by 7 to find the value of one part of the ratio.
$350 ÷ 7 = $50 ← value of 1 part of the ratio
4 parts = 4 × $50 = $200
3 parts = 3 × $50 = $150
