The equation to find a z score is (x- mean)/(standard deviation)
So, in this case the equation would be
(76-70)/(2.1)
For,
X=76
Mean=70
Standard Deviation= 2.1
After solving we find that the z score equals 2.85714
or
2.8571
We know, shortest distance between two points
and
is :

So, distance between house and library is :

Distance between library and post office :

Distance between post office and house :

Therefore, minimum distance that you can ride your bike is (5.39+7.07+7) km = 19.46 km.
Hence, this is the required solution.
I’m guessing you just need to solve it so....
6(y+3) =
= (6)(y + 3)
= (6)(y) + (6)(3)
= 6y + 18(answer)
