Caprice adds equations a and b to solve this system of equations. what makes this
approach a valid method in general for solving a system of equations?
equation a: 8x + 3y = 27
equation b: 4x – 3y = 9
12x = 36

Which best explains why this triangle is or is not a right triangle?

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Me! i will mark brainliest! i don't get polynomials and all that other stuff. so this question is really hard. multiply and simplify.(x - 4) (x^2 – 5x – 6)show your
