Answer:
-1 <= x <= 1
Step-by-step explanation:
√((1-2x+x^2)+2-2x^2)
= √((1-x)^2 + 2*(1-x)(1+x) )
điều kiện là 1 - x > =0 và 1+x >=0

Answer:
Associative Property
Step-by-step explanation:
- I would use the Associative Property because it states that you can add any numbers together no matter how they are separated or grouped (with parentheses).
- Knowing what we said in step 1, here are some other ways you can write the expression given (they are written in the steps below)
- 8 + 7 + 9
- (8 + 7) + 9
- (8 + 9) + 7
I hope this helps!
Answer:
14
Step-by-step explanation:
Number of players = 40
35% of the number of players are left handed .
So
Number of left handed players
= 35% of 40
Make 35% a decimal by dividing it by 100
= 35/100 x 40
= 0.35 x 40
= 14
14 players are left handed
Rational numbers are those numbers that are integers and can be expressed in the form of x/y where both numerator and denominator are integers whereas irrational numbers are those numbers which cannot be expressed in a fraction. ... The denominator of a rational number is a natural number(a non-zero number).
Rational numbers and irrational numbers are mutually exclusive: they have no numbers in common. Furthermore, they span the entire set of real numbers; that is, if you add the set of rational numbers to the set of irrational numbers, you get the entire set of real numbers.
Answer: If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
