P can be a range of numbers from 3 to 5.
Answer:
S=98
Step-by-step explanation:
If S2 is 196 we can divide that by two and get our answer: s=98

Step-by-step explanation:
Answer:
infinitely many solutions
Step-by-step explanation:
x + 6y = -5
3x + 18y = -15
Multiply the first equation by 3
3(x + 6y) = -5*3
3x + 18y = -15
The two equations are identical. This means they have infinite solutions along the line x+6y = -5
Since angles 3 and 4 form a linear pair, the sum of the measures of their angles must add up to 180.
We can define angle 3 as x, and angle 4 as (180-x).
x = 3 ( 180 - x ) + 4.
Solving for x, we get x=138. This is angle 3. Angle 4 is 180-138, so angle 4 is 42.
