Answer:

Step-by-step explanation:

3m^2-3n^2= 3(m^2-n^2) = 3 (m+n)(m-n)

6m-6n= 6 (m-n)

3(m+n)~(m-n)~/6~(m-n)~ = (m+n)/2

Janelle is in charge of bringing in dry erase markers for everyone in her math group to use to work on a project. She brings 3 m

Papessa [141]

Let x represent the number of students in Janelle’s group. If Janelle brings 3 markers for each person in her group, then she brings 3x markers for x students. You also know that she brings 5 extra markers for everyone to share. Thus, the total amount of markers she brings is 3x+5.

If Janelle brings in 23 markers in all, then the equation 3x+5=23 represaents the mathematical model. 

3x=23-5,3x=18,x=6

Answer: there are 6 students in Janelle's group.

A chord 20 inches long is 4 inches from the center

Lilit [14]

Answer:

The radius of the circle is 10.8 inches

Step-by-step explanation:

Given:

Length of the chord = 20 inches

Distance of the chord from the center of the circle = 4 inches

To find:

radius of the circle=?

Solution:

As shown in the figure below, the radius, r, is the hypotenuse of a right triangle. One leg of the triangle is 4 and the other is half o f20 , or 10. Using the Pythagorean theorem to calculate the length of R, as follows:

$(4)^2 +(10)^2= (R)^2$
