Answer: Domain of function is
or (0,
)
Step-by-step explanation:
Assuming x as width of rectangle
so, Width = x
Question says, Length is 5in more than 3 times id width.
we write as Length = 3x+5
Therefore, Area of rectangle will be given function f(x)
f(x) = x(3x+5)
Here, It is important to notice that width and length of rectangle will always be positive values and also, area of rectangle is always positive.
we can write in equation as


Thus, Domain of function is
or (0,
)
Answer:
- single term
- sum of 4 terms, some of which can be expanded further
Step-by-step explanation:
1. 3x
This is a single term with one variable of the first degree.
__
2. 4x + 9(2x + 1) x² + 6(-2x + 1) - 3(7 + x?)
This is a sum of 4 terms, some of which can be expanded:
- 4x
- 9(2x+1)x^2 ⇒ 18x^3 +9x^2
- 6(-2x +1) ⇒ -12x +6
- -3(7+x?) ⇒ -3x? -21
The expression can be simplified by combining like terms.
600/100=

To get it to its simpliest form, you must divide both by a common factor which is 100. 100 can go into 600, 6 times and 100 can go into 100, one time.
Which now is

=6
6 is its simplest form.
