<span>You have to calculate z-scores for each of these values and then compare them with what is needed for the 80%tile on a Normal curve.
z = (value - mean)/(standard deviation) = (value-60.0)/0.5.
z= 1 has 84% of the values smaller.</span>
Is to long to explain so I'm doing quite
find the triangle side so 2.1 square minus 1.4 square it is equal to 2.45
now you just multiple 2.45 by 2 because if you notice 2.45 is the triangle side that is missing and this is only the half so multiple by 2 for get the X value, I hope this helps you.

Answer: 5t+15</h3>
This is equivalent to 5t+5*3

5 times 3 = 5*3 = 15
Then you add up those products to get 5t+15.
This is using the distributive property.
