Answer:
Step-by-step explanation:
B/c the bigger triangle is a copy of the smaller we can say
8
/ 12 = x / 8
then, solve for x
8
(8
/12) = x
(64 *3) 12 = x
192 /12 = x
16 = x
nice, the first answer looks good , then :P
Answer:

so the answer would be c.
Step-by-step explanation:
The discriminant is the following equation:

You just simply plug in the values of the coefficients.

a = 1 (first terms coefficient)
b = -2 (second terms coefficient)
c = 5 (last terms coefficient)
This how you answer these questions. Try Answering the other 4. you Should get
2a. X=10.9
2b. C=47/5 or 9.4
3a. X=32.6
3b. X=55.7
I hope these helped
