Answer:
You "FOIL" (First, Outer, Inner, Last).
![12x^{2} - 13x - 14](https://tex.z-dn.net/?f=12x%5E%7B2%7D%20%20-%2013x%20-%2014)
Step-by-step explanation:
You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.
(3x+2)(4x-7)
(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)
12x^2 - 21x + 8x - 14
12x^2 - 13x - 14
Answer:
You would have to make and sell 600 video games.
Step-by-step explanation:
Step 1: Subtract the total cost of a game from the sell value to get the overall income from each game.
$20 - $2.65 = $17.35
Step 2: Divide the investment price in equipment by the overall income from each game.
$10,410 ÷ $17.35 = 600
Therefore, you would need to make and sell 600 video games before your business breaks even.

Answer:
The general rule of the progression is an = 3n - 10
Step-by-step explanation:
Given
Type of progression: Arithmetic Progression
a7 = 11
d = 3
Required.
The rule
First, we write out the formula of an arithmetic progression.
This is as follows
an = a + (n - 1)d
The given data is when n = 7.
So, by substituting the values in the formula above, we have
a7 = a + (n - 1)d
11 = a + (7 - 1) * 3
11 = a + 6 * 3
11 = a + 18
Make a the subject of formula
a = 11 - 18
a = -7
Having gotten the value of a, the general rule is gotten by substituting the value of a and d in the formula.
In other words,
an = a + (n - 1)d becomes
an = -7 + (n - 1)3
Open bracket
an = -7 + 3n - 3
Collect like terms
an = -7 -3 + 3n
an = -10 + 3n
Rearrange
an = 3n - 10
Hence, the general rule of the progression is an = 3n - 10
