Answer:
(fg)(x) = 6x³ - 2x² + 12x - 4
Step-by-step explanation:
( f g ) ( x ) = f ( x ) * g ( x )
f(x) = 2x² + 4
g(x) = 3x – 1
( f g ) ( x ) = (2x² + 4) (3x – 1)
= 6x³ - 2x² + 12x - 4
Answer:
The18th term of the given sequence is -128
Explanation:
To find the 18th term of the sequence:
42, 32, 22, 12, ..., we need to find the nth term of the sequence first.
The nth term of a sequence is given be the formula:

Where a is the first term, and d is the common difference.
Here, a = 42, d = 32 - 42 = -10

To find the 18th terem, substitute n = 18 into the nth term
Rectangle A has a larger area
Based on the information provided, the sum of all the labeled angles is 235° (option b).
<h3>How to calculate the sum of all labeled angles?</h3>
To calculate the sum of all the labeled angles we must add the different values of each labeled angle as shown below:
80° + 92° + 40° + 23° = 235°
According to the above, it can be inferred that the correct option is B because the result of the sum of the values coincides with this sum.
