5/3=1.6666 hope this helpssssssssssssssssssss
3 (k-12) = k-30
3k - 36 = k - 30
3k - k = -30 + 36
2k = 6
k = 3
We use quadratic formula for that one
remember that √-1=i
so
for
ax^2+bx+c=0

so
given
5x^2-6x+2=0
a=5
b=-6
c=2




Answer:
We know that angle 2 is 63. We also know that 2 and 3 are vertical pairs.
Therefor, they are congruent with one another.
Angle 3 is 63.
X=3
Explanation :-
20/5=4
8/2=4
They are both 4 so you will do
(5x-11)=4
-11+11=0
4+11=15
5x=15
15/5=3
x=3
Hope it helps
