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
Answer:
-5 and 3.
Step-by-step explanation:
-5x3=-15 -5-3=-2
Answer:
6
Step-by-step explanation:
We need to find the slope
We have 2 points
(0,0) and (1,6)
m = (y2-y1)/(x2-x1)
= (6-0)/(1-0)
= 6/1
= 6
y = 6x
The constant of proportionality is 6
All you have to do is move your decimal point over eight places to the right and then subtract that from the first number and you have your answer.
