0.7 i think. we dont do this stuff at school but
I just solved this one
anothe way is undistribute the 2 first and move -14 to side
2(x^2+6x)-14=0
comlete the squer inside and add negative
2(x^2+6x+9-9)-14=0
factor perfect square
2((x+3)^2-9)-14=0
distribute
2(x+3)^2-18-14=0
2(x+3)^2-32=0
add 32 both sides
2(x+3)^2=32
divide 2
(x+3)^2=16
sqrt both sides
x+3=+/-4
minus 3
x=-4-3 or 4-3
x=1 or -7
answer is C
A + s = 444
s = 2a
a + 2a = 444
3a = 444
a = 444/3
a = 148 <== adults
s = 2a
s = 2(148)
s = 296 ...students
