(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.

“The perimeter P of a triangle is equal to the sum of the lengths of sides a,b, and c”

Kryger [21]

Answer:

1. Write the addition of "a", "b" and "c".

2. The equation is: $P=a+b+c$

Step-by-step explanation:

You know that P represents the perimeter of the triangle and a, b and c represent the sides of the triangle.

By definition, the sum is the result of an addition. Therefore, the statement "The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c”, indicates that the perimeter is obtained by adding the lengths of the sides of the triangle.

Knowing this, you can write the following equation:

$P=a+b+c$
