The correct question in the attached figure
we know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
the answer is
the ratio x:y is 25:18
<span>We want to show that f(g(x)) = x and g(f(x)) = x.
So to do that, we need to calculate f(g(x)) and g(f(x)) explicitly.
Let's begin with f(g(x))
Now, f(g(x)) = f(4/x), by definition of g, as g(x) = 4/x
What then is f(4/x) equal to? Use the definition of f.</span>

Answer:
pi × r² × h
Step-by-step explanation:
Volume = pi × r² × h
Where pi = 3.142 (approx)
r is the radius
h is the height
<span>x^2 + 0x - 1 = 0
x^2 - 1 = 0
This is a difference of two squares which factors into the product of a sum and a difference with the pattern: a^2 - b^2 = (a + b)(a - b).
(x + 1)(x - 1) = 0
x + 1= 0 or x - 1 = 0
x = -1 or x = 1
Answer: There are two real solutions.</span>
