Answer:
Step-by-step explanation:
Note that √2x = √2*√x, and so we have √2*√x + 13 = √x + 31.
First subtract 13 from both sides, obtaining: √2*√x = √x + 18.
Next, group the √x terms together: √2*√x - √x = 18.
Now solve this for √x. We get:
√x(√2 - 1) = 18, or
18
√x = --------------
(√2 - 1)
To find x, square both sides:
18^2
x = ---------------
(√2 - 1)^2
Answer:
Not parallel.
Step-by-step explanation:
It would be parallel if its slope is also 3.
Calculate slope of line AB = y2 - y1 / x2 - x1
8 - (-2) / 3 - (-1) =
8 + 2 / 3 + 1 = 10/4 = 2.5
2.5 =/= 3, it wouldn't be parallel.
If there are 4 people at the party
1. 2. 3. 4
and each brings one gift for each other person
1. 2. 3. 4.
1. 1. 1. 1
1. 1. 1. 1
1. 1. 1. 1
1. 1. 1. 1
the number of gifts at the party is 16?
hopefully. :)
