You want to distribute and then combine the like terms, as per order of operations. Start by multiplying the 2 by -n and -3, so you get -2n-6. Then distribute the -7 to the 5 and 2n, so you get -35-14n. Combine your n’s and constants, and get -16n-41

Find the radius of a circle, given that the center is at (3,-3) and the point (7,6) lies on the circle.

Alenkasestr [34]

Answer:

$\large\boxed{radius=\sqrt{97}}$

Step-by-step explanation:

The radius is the distance between the center and any point on the circle.

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the center (3, -3) and other point on the circle (7, 6).

Substitute:

$r=\sqrt{(6-(-3))^2+(7-3)^2}=\sqrt{9^2+4^2}=\sqrt{81+16}=\sqrt{97}$

WITH PICTURE!!3. What is the value of x in the regular polygon below? (3 points)

monitta

Answer: FIRST OPTION.

Step-by-step explanation:

Regular polygons are those polygons whose sides are equal in length and whose angles are all equal.

By definition each interior angle of a Regular polygon,is:

$\frac{180 ( n -2 )}{n}$ (In degrees)

Where "n" is the number of sides of the polygon.

Observe the Regular polygon given in the exercise.

Since it has 6 sides, you can conclude that it is an Hexagon. Then:

$n=6$

Substituting into $\frac{180 ( n -2 )}{n}$ and evaluating, you get:

$\frac{180 ( 6 -2 )}{6}=120\°$

Knowing this, you can write the following equation:

$3x=120$

Finally, you must solve for "x" in order to find its value. This is:

$x=\frac{120}{3}\\\\x=40$

I have a ribbon 5/7 of a foot. I want to cut it in 5/12 pieces. How many pieces can I cut 5/7 divided by 5/12= 5/7 x5/12= 15/7 p

Otrada [13]

100 cm = 1 meter
<span>4.5 meter x 100 cm = 450 cm </span>

<span>450 cm / 4.5 cm = number of pieces of ribbon </span>

<span>450/4.5 = 100</span>
