REY [17]3 years ago

Perimeter of triangle = all sides added up
3a + 4 + 2a - 7 + 9a + 11

now add like terms
3a + 2a + 9a = 5a + 9a = 14a

4 - 7 + 11
= -3 + 11 = 8

so we have  14a + 8
as our simplest expression

I don’t get this..please help!
Maslowich

Answer:

OPTION 1

Step-by-step explanation:

You just basically plug in x and y values in all the equations and check if you get the same answer each time.

Option 1 is correct because when you plug in let's say the first coordinates,10 and 4  it does give you 6 which is right.

Or you can test it the other way, just plugging in x values and see if you get the right y value for it shown above in the table.

Hope this helps!
