Answer:

d) x=4

Step-by-step explanation:

$\sqrt{x} +5 = \sqrt{x + 45}$

$(\sqrt{x} +5)^{2} = (\sqrt{x + 45})^{2}$

$x + 10\sqrt{x} +25 = x + 45$

$10\sqrt{x} = 20$

divide 10 in both sides

$(\sqrt{x}){2} = (2){2}$

x=4

Answer:

Option C is correct.

$38 miles$

Step-by-step explanation:

Let x be the distance cover by Michelle

Given:

A circle diameter is 3 miles.

And Michelle biked around the trail 4 times.

We know that

The circumference of a circle.

circumference = $2\pi r$ ----------(1)

where $r=\frac{Diameter}{2}$

$r=\frac{3}{2} \\r=1.5$ miles

Put $\pi =3.14$ and r value in equation 1.

$circumference = 2\times 3.14 1.5$

$circumference = 9.42 mil;es$

The circumference of a circle is 9.42 miles.

And Michelle biked 4 times, that is equal to 4 $\times$ circumference.

$x = 4\times 9.42$

$x = 37.65 miles$ .

That is equal to 38 miles.

Therefore, Michelle biked around 4 trail is 38 miles.

<h3>Answer:</h3>

y = -(x -3)² +3 . . . . (agrees with your answer)
see the attachment for a graph

<h3>Step-by-step explanation:</h3>

Factoring the leading -1 from the first two terms, we have ...

... y = -(x² -6x) -6

Adding 9 inside parentheses to complete the square, then adding the opposite amount outside parentheses, we have ...

... y = -(x² -6x +9) -6 +9

... y = -(x -3)² +3
