Answer:
26
Step-by-step explanation:
Let x be the first even integer
x+2 is the second even integer
x+4 is the third even integer
The sum of three consecutive even integers is 84
x+ (x+2) + (x+4) =84
Combine like terms
3x +6 = 84
Subtract 6 from each side
3x+6-6 =84-6
3x =78
Divide each side by 3
3x/3 = 78/3
x =26
The three integers are 26, 28,30
The smallest is 26
You can use Heron Formula in the calculator to output the result, but i still show you the steps on paper thro
lengths of the 3 lines: \sqrt{392} , \sqrt{676} , \sqrt{676}
s= (\sqrt{392} + \sqrt{676} + \sqrt{676})/2=35.89949494
area= \sqrt{s(s- \sqrt{392} )(s- \sqrt{676})^2 } =238
the probability is 7/15
