Answer:
3. 0
4. n = -2
Step-by-step explanation:
I haven't taken pre-calc but this looks a lot like algebra.
For #3, just plug in -2 for the x values, so:
x^2 + 4x +4
(-2)^2 + 4(-2) + 4
= 4 - 8 + 4
= 0
For #4, move the variables to one side and solve( im not sure what the pi is for tho, or is that a n?):
5n + 6 = -3n - 10
add 3n to both sides
8n + 6 = -10
subtract 6 from both sides
8n = -16
divide both sides by 8
n = -2
Answer:
136
Step-by-step explanation:
if two angles are supplementary then they have to add up 180. So if the measure of angle 2 is supplementary to the measure of angle 4 they have to add up to 180. you subtract 44 from 180 and you get 136. The measure of angle 4 is 136. 136 makes these two angles supplementary.
