Answer:
Step-by-step explanation:
Let
![x=1.323232...](https://tex.z-dn.net/?f=x%3D1.323232...)
Multiply x by a power of
, one that keeps the decimal part of the number the same:
Subtract
from
The repeating decimals should cancel out
solve for x
Divide by
both sides
Answer:
x = 2, -4
Step-by-step explanation:
4x^2 + 8x – 32 = 0
Divide by 4
x^2 + 2x – 8 = 0
Add 8 to each side
x^2 + 2x = 8
Take the coefficient of x
2
Divide by 2
2/2 =1
Square it
1^2=1
Add it to each side
x^2+2x+1 = 8+1
(x+1)^2 = 9
Take the square root of each side
sqrt((x+1)^2) = ±sqrt(9)
x+1 = ±3
Subtract 1 from each side
x = -1±3
x = -1+3, -1-3
x = 2, -4
Answer:
4 out of 18
Step-by-step explanation:
565.32 rounded to the nearest ten is the place which has the 6. Therefore, we are seeing if 5.32 rounds up or down. Since 5.32 is greater than 5, it rounds to 10. Therefore, it rounds to 570.
Hope this helps!
