Step-by-step explanation:
plz mark brainliest even if im wrong, i really need this, and if im wrong tell me im wrong so I cant correct it
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
Ok what am I supposed to answer?
Answer:
y=7
Step-by-step explanation:
Since they are all congruent angles this means that the sides are equal too.
