Hey everyone!
i’m not sure how to complete Question 11: a)i), b)i), c)i). can you show me how i should work them out? thanks!:)

In the diagram below? p is circumscribed about quadrilateral abcd. what is the value of x

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

In a class, there are 12 girls. if the ratio of boys to girls is 5: 4 how many boys are there in the class
