2. The actual tree on the left is 10 feet tall. The model tree on the right is 8 inches tall. What is the scale factor? A: 15 B: 112 C: 1/122 D: 1/15

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

What is the radical expression that is equivalent to the expression 27 1 over 5?
