Answer:

=22n+13

Let's simplify step-by-step:

21n+15+n−2

=21n+15+n+−2

<em>Combine Like Terms:</em>

=21n+15+n+−2

il63 [147K]

Answer:

Step-by-step explanation:

Diameter:

A line passing through the center of the circle touching the circle at two points, is called diameter.

OR

The chord passing through the center is diameter.

It is double of the radius.

so,

Diameter = (2) (Radius of the circle)

Radius:

Diameter divided by 2.

OR half of the diameter is called radius.

So,

Radius = (1/2) (diameter of the circle)

Area of a circle:

Area of a circle =πr^2

Using π=3.14

Area ≈ (3.14) (radius squared)

Circumference of a cricle:

It is equal to 2πr

If π=3.14, then 2π=6.28

Circumference ≈ (6.28) (radius of the circle)

If f(6) if f(x)=x^2 / 3 + x
MakcuM [25]

Answer:

1) If the function is f(x)=\frac{x^{2}}{(3+x)}, f(6)=4

2) If the function is f(x)=x^{(2/3)}+x, f(6)=9.30

3) If the function is f(x)=\frac{x^{2}}{3}+x, f(6)=18

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

f(6) means that you must substitute x=6 into the function above.

1. If the given the function f(x)=\frac{x^{2}}{(3+x)}, you obtain:

f(6)=\frac{6^{2}}{(3+6)}=4

2. If the function is f(x)=x^{(2/3)}+x

Then:

f(6)=6^{(2/3)}+6=9.30

3. If the function is f(x)=\frac{x^{2}}{3}+x

Then:

f(6)=\frac{6^{2}}{3}+6=18
