Answer:
the factors of x^3-1 are 
Step-by-step explanation:
We need to find factors of x^3 -1
So, the factors of x^3-1 are
A rational number is a number that can be made by dividing two integers. An integer is a number that doesn't have a fraction part.
1. 2.4 - rational
2. 74 - rational
3. 17.3333333… - rational
4. π -irrational
5. there is no number
6. –18 - rational
7. there is no number
8. 87.125 - rational
9. –30 - rational
10. –8.3 -rational
11. 58.25 -rational
12. 121 -rational
13. 4.5 -rational
14. 3 7/10 -rational
As you can see, most numbers are rational. But, when you come across pi or when you have a decimal that goes on forever without repeating (like some square roots), it tends to be irrational.
Answer:
13
Step-by-step explanation:
3y + 6 ÷ 2x = 3(4) + 6 ÷ 2(3) = 12 + (6 ÷ 6) = 12 + 1 = 13
Answer:
56 degree
Step-by-step explanation:
90 - 34 = 56
Answer:
<U= 75°
<V=65°
x=50
Step-by-step explanation:
The interior angles to a triangle always equal 180°.
Set up your equation:
180= 40+x+15+x+25
Subtract 40 from 180 to get 140. Subtract 15 from both sides. Now you have 125. Subtract the 25 from both sides. You now have 100.
Divide the 100 by 2 to find what x is because your equation is now 100=2x
x=50
v= 50+15= 65 so V is 65°
U is 50+25 so U is 75°
