Answer:
10/13
Step-by-step explanation:
You will first add all the students the mentioned which gives you 13 then since they ask what is the probability it the teacher would pick girls. You know there's 10 girls and 3 boys so it would be 10/13.
The factor is (x+6)(x+6)
So, D. x+6 is the correct answer :)
Recall that
sin²(<em>x</em>) = (1 - cos(2<em>x</em>))/2
so that
sin²(7<em>π</em>/8) = (1 - cos(7<em>π</em>/4))/2
sin²(5<em>π</em>/8) = (1 - cos(5<em>π</em>/4))/2
Then
sin²(7<em>π</em>/8) + sin²(5<em>π</em>/8) = (1 - cos(7<em>π</em>/4) + 1 - cos(5<em>π</em>/4))/2
… = 1 - 1/2 (cos(7<em>π</em>/4) + cos(5<em>π</em>/4))
… = 1 - 1/2 (1/√2 - 1/√2)
… = 1
Width is x.
Length is (x + 1).
Area = length*width
56 = x(x+1)
x² + x - 56 = 0
(x+8)(x-7)=0
x = - 8, or x = 7
"- 8" is impossible for width.
So, width x = 7
Length = (x+1) = 7+1 = 8
