Answer: -406
Step-by-step explanation:
We have the following expression:
In addition we know:
and 
If we substitute this in the expresion, we will have:
Let the radius of the circle be r. Then the line from the external point through the center of the circle which extends to the far point on the circle has length 3r .By the tangent - secant theorem
t^2 = 3r * r = 3r^2 ( where t is the length of the tangent).
So t = √(3r^2) = √3r answer.
Answer:
(-4+2*2)+8
Step-by-step explanation:
2*2=4
-4+4= 0
0+8= -8
If someone reads the book (Gryphon) by Charles baxter what???
Ok, so 11:9
11-9 = 2
which means that 124= 2:1
124/2 = 62
so 62:0
now 11 x 62= 682
9 x 62= 558
so the ratio is 682:558
now 682 + 558 = 1,240
There are 1,240 total students in the school. 682 boys and 558 girls
