Triangles add up to 180. So add up the two angles given, and subtract that from 180. That will be x!
Answer:
Step-by-step explanation:
= 2k - x
Given that k = 9, x = 5
= 2(9) - 5
= 18 - 5
= 13

Answer:
-3s^2+16s-7
Step-by-step explanation:
-3s(s - 10) + 7(-2s -1) --> (-3s^2+30s)+(-14s-7) ---> -3s^2+16s-7
DO multiplication them convert like terms
The vertex is the point at which the parabola or quadratic equation opens up or down. To calculate the parabola, we must use the formula: -b/2a = x; x = -16/2(4) x = -2
Substitute -2 in where you see x appear and do the arithmetic to find that y = -15. Therefore, the vertex coordinates are (-2,-15).
Looks like the answer would be 219 people since you can't have half a person.
