Answer:
15
Step-by-step explanation:
5x4=20
5x-1=-5
20-5=15
712/34 divide it then you have your answer :)
Here's the solution,
<u>figure</u> 1.
by using trigonometry,
=》

=》

=》

=》

=》

And,
=》

=》

=》

So, values are :
<u>figure</u> 2.
Since, it's an isosceles triangle, w = y,
So, by pythagoras theorem :
=》

=》

=》

=》

=》

=》

and we know, w = y, so their values will be equal to 7 units.
Answer:
D) x^2 + 4x - 21 = 0
Step-by-step explanation:
--------------------------------------------
Given information
--------------------------------------------
Red balls = 6
Green balls = 5
--------------------------------------------
Find total
--------------------------------------------
Total balls = 6 + 5
Total balls = 11
--------------------------------------------
Find probability
--------------------------------------------
G = green
R = red
P (R+ G + G) = 6/11 x 5/11 x 5/11 = 150/1331
P (G +R + G) = 5/11 x 6/11 x 5/11 = 150 /1331
P (G +G + R) = 5/11 x 5/11 x 6/11 = 150 /1331
Total probability = 150/1331 + 150 /1331 + 150 /1331 = 450/1331
--------------------------------------------
Ans: The probability is 450/1331
--------------------------------------------
