Answer:
4b -11 = 1 -2(3-b) (use the distributive property on -2(3-b))
4b -11 = 1 -6 +2b ( combine like terms on the right side of the = sign)
4b -11 = -5 +2b (subtract 2b from both sides)
2b -11 = -5 (add 11 to both sides)
2b = 6 (divide each side by 2)
b= 3 ( so, your answer is C)

<u>Triangles And Circles</u>
If a right triangle is inscribed in a circle (or the circle is circumscribed around the right triangle), then the hypotenuse of the triangle is the diameter of the circle.
The right triangle has both legs of known lengths, thus the hypotenuse (the diameter of the circle is):
Since 50=2*25:
Thus the radius of the circle is:
Area = base x height /2
Base =26.5
Height =40
26.5 x 40 /2 = 530
The answer is 12.5 meters per seconds
