Answer:
b^2 - 6b - 55
Step-by-step explanation:
(b + 5)(b - 11)

F: b * b = b^2
O: b * -11 = -11b
I: 5 * b = 5b
L: 5 * -11 = -55
b^2 - 11b + 5b - 55
Combine like terms
-11b + 5b = -6b
b^2 - 6b - 55
3 Is B. The formula for finding the area of a circle is A= r(to the second power) times Pi. The radius is 6, so you must do 6 to the second power which is 6 times 6. That is 36. Your answer will be 36 pi.

Answer:
20° and 70°
Step-by-step explanation:
complimentary angle sum to 90°
let x be the compliment then the angle is 3x + 10 , so
x + 3x + 10 = 90 , that is
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
3x + 10 = 3(20) + 10 = 60 + 10 = 70
the 2 angle measures are 20° and 70°
