Answer:
14d + 12c -4
Step-by-step explanation:
The 3 inside angles of a triangle need to = 180 degrees
you are given 70 and 80 which = 150 degrees ( 70 +80 = 150)
so the missing angle (PQR) = 180 - 150 = 30 degrees
In this question, it is given that
The population of a particular village can be modeled by the equation

where x is the number of years since 1990.
And we have to find in what year were there 1706 people living in the village?
So we put 1706 for y and solve for x. That is

Subtracting 56 from both sides.

And 1990 +15=2005
Therefore in 2005, there were 1706 people living in the village
Answer:
1/4
Step-by-step explanation:
