Equations and inequalitiesi just need plz 50=2×+12

The standard distance between studs in a house is 1.5 feet. if you have a set of blueprints for a house that mark every 1.5 feet with 2 in., by how many inches will a 13-foot wall be represented?

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12
