Answer:
2880 ways
Step-by-step explanation:
There can be only one arrangement in which boys and girls can sit.
G-B-G-B-G-B-G-B-G
but position of individual boy and girls can be changed.
So, there are 5 girls and 5 slots for them that means they can be arranged in 5! ways,
similarly boys have 4 slots, so they can be arranged in 4! ways.
now, one more thing to consider is that out of 5! arrangements of girls, with each arrangement boys can be arranged in 4! different positions.
so to get the total number of boys and girls arrangements together we would need to multiply the arrangements of both boys and girls.
so the desired answer would be: 5!*4! = 120*24 = 2880 ways.
Answer:
use identity (a - b) ^3 = a^3 - b^3 - 3ab (a - b)
here, a = x ^2
b = -1
= (x^2)^3 - (-1)^3 - 3 * x ^2 * -1 ( x^2 - (-1) )
x^6+ 3 x^2 ( x ^2 + 1)
I think this is the answer
(6,5) is the only pair that you will find in the table.
Answer: B, Each of the sums is 180 degrees.
Step-by-step explanation:
Since a 180 degree angle is always a flat line, and that is the case for this,
Each of the sums is 180 degrees.
Hey there!!
Given equation :
... 2 ( x - ( 3 + 2x ) + 9 ) = 3x - 8
Using the distributive property.
... 2 ( x - 3 - 2x + 9 ) = 3x - 8
... 2 ( -x + 6 ) = 3x - 8
Using the distributive property.
... -2x + 12 = 3x - 8
Subtracting 12 on both sides.
... -2x = 3x - 8 - 12
... -2x = 3x - 20
Subtracting 3x on both sides.
... -2x - 3x = -20
... -5x = -20
Dividing by -5 on both sides.
... x = -20 / -5
... x = 4
<em>Hence, the answer is 4. </em>
Hope my answer helps!
