I'm actually doing this quiz right now, so I'll let you know what the answer is.
The ladder resting against the house forms a triangle similar to the one in the image below
To answer this question you must use Pythagorean theorem

a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = x
b = 4
c = 20
^^^Plug these numbers into the theorem

solve for x
+ 16 = 400
= 384
x = 8√6
or
x ≈ 19.5959....
Hope this helped!

Step-by-step explanation:
To find a ratio, you have to divide a next terms with before terms.
A1 = 35/2
A2 = 7
ratio = A2 ÷ A1
ratio = 7 ÷ 35/2
ratio = 7 × 2/35
ratio = 14/35 = 0,4
Ratio = 0,4
Answer:
(-9, -3) - Interval over which the difference of the numbers of sales is negative.
(4.9, 10 ) - Interval over which the difference of the numbers of sales 15 positive
(-3, 10) - Interval over which the difference of the numbers of tale decreasing
(0, 4.9) - Interval over which the difference of the numbers of sales is increasing
