Answer:Real numbers are used in measurements of continuously varying quantities such as size and time, in contrast to the natural numbers 1, 2, 3, …, arising from counting. ... The real numbers include the positive and negative integers and fractions (or rational numbers) and also the irrational numbers.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
multiply the 1st equation by -3
The correct answer is 6 - sqrt(6)
We know this because when we solve with the quadratic equation, the numbers come out with a constant plus and minus the discriminant under a square root symbol. You can see that below in the quadratic equation.
So seeing that one answer is 6 + sqrt(6), we can assume 6 is the discriminat and 6 is the constant. Thus giving us the new answer as well.
Gcf of 6 and10 is 2.
Gcf of 15a^3, 20a^2 is 5a.
Gcf of ab , a^2 b^2 is ab.
To find the Gcf of exponents;
Take a^3-a^2
A cancels each other out
3-2=1
A represents 1.
ab, a^2b^2
a^2 b^2- ab
A and b cancel each other out.
2-2=0
So you are left with a and b to represent your exponents.
Hope that made sense.
Also in the pic is a explanation in how to find the Gcf for normal numbers!
Hope this helps you!
2 1/4 + 1 2/4 ≠ 5
Why?
2 1/4 + 1 2/4
=3 3/4
The answer is wrong because the student added wrong. The real answer is 3 3/4.
