Answer:
More cereal
Step-by-step explanation:
Seems to be aritmetic
an=a1+d(n-1) is aritmetic
a1=fist term
d=comon difference
n=which term
a4-a2=2d where d is the common difference
26-14=12
12=2d
6=d
so
a2-6=a1
14-6=8
an=8+6(n-1)
expand
an=8+6n-6
an=6n+2
3rd option
Step-by-step explanation:
let the total students be x then
25/100x=9
x=9×100/25
x=9×4
x=36
so total students are 36
X^2-18x__=-34
X^2-18x+(18/2)^2=-34
X^2-18x+81=-34+81
(X+9)^2=47
(X+9)^2-47=0
