(f g)(x) means f(x) * g(x), so plug the value of each function in:
(x+2)(x-4)
And solve by distributing using FOIL:
Firsts: x * x = x²
Outers: x * -4 = -4x
Inners: 2 * x = 2x
Lasts: 2 * -4 = -8
Combine them all together:
x² - 4x + 2x - 8
Combine like terms (the -4x and 2x):
x² - 2x - 8
So the second to last one is correct.
Based off of inferring that you meant angles rather than "lengths"...
All angles of any triangle must add up to 180<span>° to be classified as a triangle.
Therefore NO, given that the triangle provided adds up to 252</span><span>° </span>
Answer:
7800m & 1600 milligrams
Step-by-step explanation:
Hypotenuse² = 3^2 + 10^2
hypotenuse² = 9 + 100
hypotenuse² = 109
