X=2
As both triangles share a same side length of 5, and the angles are both 30degrees, assuming the triangles meet at the centre of the circle then both sides (x) must be the same.
Answer:
-11
Step-by-step explanation:
Plug in -2 for x
5(-2) - 1
Order of operations (or PEMDAS) tells you to multiply first giving you:
-10 - 1
-10 - 1 = -11
2 (n+1) + n² + 4 (n-3)
= 2n + 2 + n² + 4n - 12 ...expand by using distributive property
= n² + 6n - 10 ...combine like terms
