Answer:
Step-by-step explanation:If you choose any 3 of the 7 vertices, you can connect them with lines to create a unique triangle.
So, the question becomes "In how many different ways can we select 3 vertices from 7 vertices?"
Since the order in which we select the 3 vertices does not matter, we can use COMBINATIONS.
We can select 3 vertices from 7 vertices in 7C3 ways.
The equation would be worded as: 2m+16=36.
Solve! Using the subtraction property of equality, 2m=20. Then the division property of equality lets us figure out that m=10.
Hope that helped! Happy SOLVING!
Answer:
<h2>x < - 2</h2>
Step-by-step explanation:
First subtract 7x from both sides of the inequality
That's
<u>Add 10 to both sides of the inequality</u>
<u>Divide both sides by - 15</u>
Since the denominator is negative the sign will change
We have the final answer as
<h3>x < - 2</h3>
Hope this helps you
