We can find an unknown angle in a triangle by applying the fact that total interior angles of a triangle is 130 degree. True or False

If an x intercept only touches the x axis it means it has a multiplicity of 2. if an intercept goes through the axis it has a multiplicity of 1 true false

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Solve 4 ln x=2ln25 a) x=5 b) x=25 c) x=625
