Answer:that would be x=8
Step-by-step explanation:
Answer:
3 am
Step-by-step explanation:
Time in hell : Time on Earth
120 : 1
50 : x
120/50 = 1/x
x = 5/12 years
Since,
1 year = 365 days and 1 day = 24 hours
In hours,
5/12 × 365 = 152 1/12 days
152 days after 1 am, would be 1 am.
1/12 days which is also 2 hours later, it would be 3 am.
1/12 day × 24 = 2 hours
Answer:
Assuming you want to simplify the expression, it can be shortened to:
-k² - 2k
Step-by-step explanation:
What you need to do here is called grouping like terms. Like terms can be described as terms that have the same factors. In this case, the factors we're looking at are k and k²:
Given:
k - 3k² -3k + 2k²
We'll rearrange to group like expressions:
= -3k² + 2k² + k -3k
Pull out common factors:
= (-3 + 2)k² + (1 - 3)k
And simplify:
= -k² - 2k
The answer is Difference of Cubes.
Difference of cubes is a³ - b³.
27 can be written as 3³ (= 3 × 3 × 3 = 27). So, a = 3.
8 can be written as 2³ (= 2 × 2 × 2 = 8). So, b = 2.
Difference of cubes can be expressed as:
a³ - b³ = (a - b)(a² + ab + b²)
⇒ 3³ - 2³ = (3 - 2)(3² + 3×2 + 2²) = 1 × (9 + 6 + 4) = 1 × 19 = 19
⇒ 27 - 8 = 19
