Does anyone else have trouble with math
For me I understand math but at the same time I don’t

Common binomial factor of 6x(3x+7)+5(3x+7)

Given a normal distribution with µ =50 and σ =4, what is the probability that 5% of the values are less than what x values? between what two x values (symmetrically distributed around the mean) are 95 % of the values? instructions: show all your work as to how you have reached your answer. don’t simply state the results. show graphs where necessary.

Given the equation −4  = 12, solve for x and identify if it is an extraneous solution.
