Enter your answer in the box.

The distributive property allows you to say that 3(x − 1) = 3x −

What is the factored form of the following expressions? d^2 – 13d + 36

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
