Answer:

f(x)= \frac{7}{x}+10 and g(x)=x^2 

Step-by-step explanation:

Given : Equation y=\frac{7}{x^2}+10.

To find : f(x) and g(x) so the function can be expressed as y = f(g(x)) ?

Solution :

Our aim is to express f as a function of g, where g is a function itself, of x.

In the expression,

y= \frac{7}{x^{2}}+10

We may notice two functions, the squaring x function, which may well be our g i.e. g(x)=x^2 

The function is re-written as, y= \frac{7}{g(x)}+10

and the "7 divided by x, +10" function is  f(x)= \frac{7}{x}+10

Therefore, f(x)= \frac{7}{x}+10 and g(x)=x^2.

Given y = 7/x² + 10

Let,

y = f(x)

f(x) = 7/x² + 10

And,

g(x) = x²

Hence, f(g(x))

Reason is;
You have to rewrite f(x) so that it can fit in g(x) into the equation

f(x) = 7/g(x) + 10

the perimeter of a square is equal to the perimeter of an equilateral triangle the length of a side of the square is given by th
diamong [38]

Answer:

x = 3

Step-by-step explanation:

We are told that the length of a side of the square is x.

Now, perimeter of square = 4 × side length

Perimeter of square = 4x

Also,we are told that the triangle is equilateral and a side is (x + 1).

Thus, perimeter of triangle = 3(x + 1)

Since we are told that the perimeter of the square is equal to that of the equilateral triangle. Thus;

4x = 3(x + 1)

4x = 3x + 3

Subtract 3x from both sides to get;

4x - 3x = 3

x = 3
