5 . x^2 /x^2 for x=2

goblinko [34]

Answer:

1

Step-by-step explanation:

Hello!

Plug in 2 for x and simplify.

<h3>Evaluate</h3>

$\frac{x^2}{x^2}$
$\frac{2^2}{2^2}$
$\frac44$
$1$

We could have also simplified the fraction first. If a fraction has the same number in the numerator and the denominator, then it is always equal to 1, no matter what values of x.

snow_lady [41]

Circumference of a circle = $\pi$ (diameter)

Diameter = 23 in.

Plug in the diameter = 23 in in the formula of circumference given above

Circumference of a circle = $\pi$ (23)

Circumference of a circle = 23 $\pi$

$\pi$ = 3.14

Circumference of a circle = 23 (3.14)

Circumference of a circle = 72.22 in
