Step-by-step explanation:
This may be the answer to your equation.
Answer:
The simplified expression is: 12(7m - 6n)
Step-by-step explanation:
Greatest common factor between 84 and 72
We keep dividing 84 and 72, while they can be divided by the same factor. So
84 - 72| 2
42 - 36|2
21 - 18|3
7 - 6
So the greatest common factor is 2*2*3 = 12.
Rewrite 84m - 72n as a product of two factors
Evidencing 12

Answer:
Segment AD is 3, and segment AE is 2.
Step-by-step explanation:
In a triangle, the line joining the mid points of two sides is parallel and half of the third sides of the triangle.
Here, ABC is a triangle,
In which,
AB = 6,
AC = 4,
D∈ AB and E∈AC
Let DE ║BC,
And, 
In triangles ADE and ABC,
( Alternative interior angle theorem )

By AA similarity postulate,

∵ Corresponding sides of similar triangle are in same proportion,





Hence, the correct option would be,
Segment AD is 3, and segment AE is 2.
Answer:
Option C (1, 0)
Step-by-step explanation:
We have a system with the following equations:

The first equation is a parabola.
The second equation is a straight line
To solve the system, substitute the second equation in the first and solve for x.

Simplify

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.
These numbers are -1 and -1
Therefore

Finally the solutions are

From 2:30-3:30 is 1hr and from 3:30-4:00 is 30 min from 4:00-4:15 is 15 minutes
Add up these time you get 1hr and 45min
