X^2+12x+6=0 subtract 6 from both sides...
x^2+12x=-6 halve linear coefficient, square it, and add it to both sides...
x^2+12x+36=30 now the left side is a perfect square...
(x+6)^2=30 take square root of both sides...
x+6=30^(1/2) subtract 6 from both sides...
x=-6-30^(1/2) and -6+30^(1/2)
Answer:
Y=8x
Step-by-step explanation:
5/6 = 0.833333 .... (non-terminating)
It would be between the 3 m and the 4 m
hope this helps :)
I cant see the question 1 sorry:(
2. x=71(base angle, isos. triangle)
3. x=45 (same reason as the above)
4. the third one
