This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
Hope this helps!
To find the average, add all numbers together and divide by the amount of numbers there are
(85 + 92 + 84 + 85 + 96 + 95)/6 = 537/6 = 89.5
you're answer is 89.5 as average
hope this helps
You have to multiply -2 to all of the numbers inside the parenthesis and you will have your answer. -6v+4x+2
I believe it is 1250
Explanation: Area of a triangle=1/2bh-1/2•20•30
Area of square=bh-25•25
Add your answers together then you get 1250
