Answer:
x = -4 + 3√2 and x = -4 - 3√2
Step-by-step explanation:
Complete the square of x^2+8x-2=0:
Between 8x and -2, write in 4^2 - 4^2, so that we now have:
x^2 + 8x + 16 - 16 - 2 = 0, or by writing x^2 + 8x + 16 as the square of a binomial, (x + 4)^2 = 18
Taking the square root of both sides, we get:
x + 4 = √18 = ±√9√2, or ±3√2
Then x = -4 + 3√2 and x = -4 - 3√2
3x(1.05) = 3.15x
1.05x + 1.05x + 1.05x = 3.15x
Answer:
26 + 18 = 44 and 18 + 34 = 52.

hopefully this helps! i don't kno if they covered this subject in school though for me.
Answer:
CPCTC
Step-by-step explanation:
You already proved that triangle BAD is congruent to CAD, this means that all of the corresponding angles and sides with be congruent (CPCTC). That means BD is congruent to CD. Hope this helps!
