Please help! Simple math! Will give brainliest! Write an equation where a number is added to a variable, and a solution is -8. Thank you!

An assembly consists of two mechanical components. suppose that the probabilities that the first and second components meet specifications are 0.87 and 0.84. assume that the components are independent. determine the probability mass function of the number of components in the assembly that meet specifications. x

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Rewrite 9 log, x2 in a form that does not use exponents. 9log, x = log, x
