The area of a triangle is given in terms of the side lengths (b, h) as
... A = (1/2)bh
If b=h, then we can find the side length as ...
... A = (1/2)b²
... b = √(2A) . . . . . multiply by 2 and take the square root
The hypotenuse (x) can be found from the Pythagorean theorem:
... x² = b² + h² = 2b²
... x = b√2
The perimeter is the sum of the side lengths, so is
... P = b + b + x = 2√(2A) + (√(2A))·√2
... P = (2+√2)·√(2A)
Subtract 25 from 85 and that is your x
X = boy count
x + 14 = girl count
x +x +14 = 86
2x + 14 = 86
2x = 72
x = 36
x + 14 = 50
There are 36 boys and 50 girls. Hope this helps!
Answer:The correct answer is:
f(2) = g(2) and f(0) = g(0)
Explanation:
If f(x) = g(x), this means the values of the functions are the same when using the same numbers. That means if we use 2 for x, then f(2) would need to be equal to g(2); if we use 0 for x, then f(0) would need to be equal to g(0). This is the case in this option, so this option is correct.
