let the number be x
so by the question , 2x+5=13
solving this we get ,
2x=13-5
2x=8
so x=4
Answer:
1) vertical-Line test
2)y=x
3)x
4)domain
Step-by-step explanation:
the axis of symmetry is x=2
According to the problem, the length is 2 feet more than its width, which is expressed as the following function

If the width is x, then the length is x+2.
We can express the following function for the area

Let's replace the width x = 11 ft.

<h2>Hence, the area is 143 square feet. </h2><h2>The function for the area is</h2>

Where x represents the width.
It will be as cold as -12 degrees Fahrenheit
(That’s pretty cold....)
That’s because 5 - 17= -12
Hope this helps :)
