Answer:
Length: 48
Width: 12
Step-by-step explanation:
Substition
l - 2w = 24
I = 60 - w
60 - w - 2w = 24
60 - 3w = 24
-3w = -36
w = 12
Substitute it into the equation to get the length.
l = 60 - 12
l = 48
Number (x) 1 -1 2 -2
Fourth power of the number (y) 1 1 16 16
(a) Does the table represent y as a function of x?
From the table we can see that every x value has a corresponding y value
The x values are not repeating. So It is a function.
If we graph the table then it will pass vertical line test.
B: The total cost f(x), in dollars, for renting a truck for x hours is shown below: f(x) = 17x + 50 What is the value of f(30) and what does f(30) represent?
Total cost f(x) = 17x + 50
To find f(30), we plug in 30 for x

The rent of the truck for 30 hours is $560
This kind of decimal is called a terminating decimal, meaning it ends rather than repeating on forever like this one: 4.5555555555...... or the fraction 2/3 when you turn it into a decimal.
Step-by-step explanation:
Given
6x² + 5x + 1
= 6x² + ( 2 + 3)x + 1
= 6x² + 2x + 3x + 1
= 2x ( 3x + 1 ) + 1 ( 3x + 1)
= ( 3x + 1) ( 2x +1)
Hope it will help :)
