Answer:
1.x=13/8-3y/8
2.x=11/3-2y/3
Step-by-step explanation:
Well x is an obtuse angle
but the angle e,f,g is an acute angle
It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
2n^2 + 4n + 2 = 0
Divide both sides by 2:
n^2 + 2n + 1 = 0
Find two numbers that multiply to form C (1) and add together to form 2: these numbers are 1 and 1:
(n +1)(n+1) = 0
(n+1)^2 = 0
Therefore n+1 = 0
n = -1
