A drawing has a scale of 1:40 On the drawing, a kitchen is a rectangle measuring 14cm by 22cm.
A bedroom has an actual area of 500,000 cm ^2.
How much smaller, in cm^2 is the kitchen than the bedroom?

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

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 total area of the figure?
