Question 6: $38.82
question 7: t=5w
question 8: which blood type does the leaf number of people have
The answer is -8/15. This is a for sure correct answer.
X^2+x-30 -- find two numbers that add to one and multiply to -30, which would be 6 and -5. so now you have x^2+6x-5x-30. factor out x and 5 to get x(x+6)-5(x+6). so you get (x+6)*(x-5)
If I understand it correctly then its complementary angle will be 115˚, because 180-65=115.
