<h2>Answer:</h2>

The answer is 16.

<h2>Step-by-step explanation:</h2>

Since the 8x is positive, the equation  must have y as a positive number.

Let's see this!

An easy way to complete the square if you have the constants for x2 and

But not the non-variable number is to divide the x constant, and then square it.

Example:

\frac{8x}{2} \\\\4^2=16\\

The last number must be 16. Let's check it.

(x+4)^2=x^2+8x+16

For f (x) = 3x +1 and g(x) = x^2-6, find (g/f)(x)
sp2606 [1]

Answer:

(g/f) (x) =\frac{x^2-6}{3x+1}

Step-by-step explanation:

We have the following functions

f (x) = 3x+1

g (x) = x^2-6

To find (g/f)(x) we must divide the function g(x) with the function f(x)

Then we perform the following operation

(g/f) (x) =\frac{x^2-6}{3x+1}

Finally we have that:

(g/f) (x) =\frac{x^2-6}{3x+1}

For x \neq -\frac{1}{3}

I can’t figure out what the half circle means the answer options are 163,129,149 and 186
vodka [1.7K]

Answer: 129

Step-by-step explanation: First find the area of the circle. Since we know the area of a circle is πr²  (pi multiplied by the radius squared) we can find the area of the half circle. The radius is 5 (because radius is half of the diameter)

Area=3.14(5)²

       =3.14(25)

       =78.5

But since this is just a half circle, divide this by 2

That will get 39.25

Then add this to the area of the rectangle (L*W) which is 90

That will get about 129
