The three integers are x, x+2, x+4

5(3x+6)=42+x(x+2)
15x+30=x^2+2x+42
x^2 - 13x +12=0
(x-12)(x-1) = 0
x = 12 or 1
since the integers have to be odd we exclude 12

integers are 1,3,5

3b-14/3b = 5b+2/3b <br> b= ?
WINSTONCH [101]

First of all, observe that all fractions exist as long as b is not zero.

Multiply both numerator and denominator of the first fraction by 3:

\dfrac{3b-15}{3b}+\dfrac{1}{3b}=\dfrac{5b+2}{3b}

Now all fractions have the same denominator. Under the assumption that b is not zero, multiply both sides by 3b:

3b-15+1=5b+2 \iff 3b-14=5b+2

Subtract 3b from both sides:

-14=2b+2

Subtract 2 from both sides:

-16=2b

Divide both sides by 2:

b=-8

The area of the circle would be (taking the value of pi as 3.14) is 200.96 square centimetres

The area of the shaded region would be 256 - 200. 96 = 55.04 square centimetres
