<u>Given</u>:

The rectangle has a height of 4x and the width of $3x+1$

We need to determine the area of the entire rectangle.

<u>Area of the rectangle:</u>

Let us determine the area of the rectangle.

The area of the rectangle can be determined using the formula,

$A=length \times width$

Substituting the value length = 4x and width = $3x+1$ in the above formula, we get;

$A=4x(3x+1)$

Let us remove the parenthesis by multiplying the term 4x within the bracket, we have;

$A=12x^2+4x$

Thus, the entire area of the rectangle is $12x^2+4x$

9/17 15/34 6/17 9/34 geometric sequence?

zysi [14]

In a geometric sequence each number after the first is found by multiplying the previous number by a fixed number called the common ratio.

In an arithmetic sequence, each term is equal to the previous term plus or minus a constant called the common difference.

In your problem we have a sequence of numbers that appears to be decreasing in value, but on the surface it doesn't appear to be by any constant number... but if you look closely, the denominator 34 is exactly twice the other denominator 17. This would lead me to look at a common denominator to see if anything takes shape...

9/17 = 18/34
15/34
6/17 = 12/34
9/34

Now we see that each number is the previous number minus 3/34, so we have a common difference of 3/34.

This would match the definition of an arithmetic sequence and NOT a geometric sequence.

Function g is a transformation of function f.

bulgar [2K]

The equation of function g(x) in terms of f(x) is g(x) = -3[f(x)].

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given:

genera form of an exponential function is y=aeᵇˣ

Now, equation for f(x) is

f(x) = $e^{(log \;2)x} -2$
