Someone

circle o has radius 4 cm, and circle phas radius 6 cm.
the centers of the circles are 8 cm apart. if the circles
intersect at a and b, find the blue shaded area

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
