Let f(x) be the real value function. Remember that:
→ Even: f(x) = f(-x) → Odd: -f(x) = f(-x)
If -f(x), then -f(x) = -x³ + 5x If x = -x, then f(-x) = -x³ + 5x
Since -f(x) = f(x), the function is therefore odd.
Answer: x = 29
Step-by-step explanation:
The four angles of a Parallelogram equal to 360. Its name is derived from the fact that its made up of two sets of parallel lines which means that its opposite angles are equivalent. Fortunately, you are given the values for the angles that are not equivalent which means you can create an equation and solve for x.
5x - 23 + 5x - 23 + 2x + 2x = 360
14x - 46 = 360
14x = 406
x = 29
Find the area of the base:
(4)(3) = 12sqft
Find the area of the sides:
(4)(12) = 48sqft
There are 2 bases and 4 sides, therefore:
12(2) + 48(4) = 24 + 192 = 216sqft
Hope this helps :)
