Answer:
78
Step-by-step explanation:
Since the two angles at the bottom are congruent, you would the two equations equal to each other. So it would be:
5x-19=2x+11
Once you simplify, you will find that x= 10.
Then you plug in x for both equations, so 5(10)-19= 31 and 2(10)+11= 31
So you add up the sides: 31+31+16= 78
If you are being serious it's 19
Answer:
s=√7-1
s=-(√7+1)
Step-by-step explanation:
s^2+2s-6=0
or,s^2+2.s.1+1^2=6+1^2
or,(s+1)^2=6+1
or,(s+1)^2=7
or,(s+1)^2=(±√7)^2
or,s+1=±√7
either,
s=√7-1
or,
s=-(√7+1)
Nico is the subject in the sentence because he is the character and ran is the predicate because it's a verb.
