Answer:
D and E
Step-by-step explanation:
x² = 15 ( take square root of both sides )
x = ±
that is
x = , x = -
A+b+c= 3932
a=b+1330
a=c+1740 ⇒c=a-1740⇒c=(b+1330)-1740
Obt.
b+1330 +b+(b+1330)-1740=3932 ⇒3b+2660-1740=3932⇒3b+920=3932⇒3b=3932-920⇒3b=3012⇒b=3012/3⇒
a=b+1330⇒a=1004+1330⇒
c=a-1740⇒c=23334-1740⇒
