Step-by-step explanation:
The trinomial x² +8x +16 is a perfect square trinomial, so factors as ...
x² +8x +16 = (x +4)²
Assuming the side length is one of the factors of the given area, it will be ...
side length = (x +4)
F(x) = x^2 + 3 is a function.
domain of f(x) = x^2 + 3 is all real numbers.
range is all real numbers greater or equal to 3.
x = cos (47) = Pi/3, cos 47 = X/3
Step-by-step explanation:
x = 2.05, 2.05 (2.05)²
