The circumference of a rhombus is 52 cm, and the sum of the lengths of its diagonals is 34 cm. What is the obtuse angle of a rhombus?

Put the equation in slope intercept form by solving for y

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

Serena is making an experiment. for that, she needs 20 grams of a 52% solution of salt. she has two large bottles of salt water: one with 40% and the other with 70% of salt in them. how much of each must she use to make the solution she needs? i am in need of
