Answer:
6x² - 7x - 3
Step-by-step explanation:
(f × g)(x) = f(x) × g(x), that is
(2x - 3)(3x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(3x + 1) - 3(3x + 1) ← distribute both parenthesis
= 6x² + 2x - 9x - 3 ← collect like terms
= 6x² - 7x - 3

Answer:
(-2,-2)
Step-by-step explanation:
The local minimum is a turning point of the graph.
From the graph, there is a turning point at (-2,-2).
This is the local minimum on the interval (-6,2).
This is the least point this interval.
That is why it is called local minimum.
Answer:
29 rungs
Step-by-step explanation:
In this question, we are to use the climbing statistics of a firefighter to determine the number of rungs a ladder have.
Firstly, since we do not know the number of rungs but we know we are starting from the middle rung, let the middle rung be r.
From the middle rung, he climbed 6 rungs, meaning he would be on rung x + 6 ! From here he came down ten rungs, meaning he would be on rung x + 6 - 10 = x -4
Now, he climbed 18 rungs again, making x -4+18 = x + 14
This is equal to the topmost rung i.e the topmost rung is at a position x + 14
This means that the ladder must have 14 rungs above the middle , 14 below it and the middle itself
14+ 14 + 1 = 29 rungs
