) Figure shows a triangle and a rectangle. The triangle has sides of length x cm, (2x – 2) cm and(x + 1) cm. The rectangle has length (2x + 3) cm and width (x + 3) cm. The perimeter of the rectangle is 3 times the perimeter of the triangle.(a) Write down an equation in x to represent the given information.(b) Solve your equation to find the value of x. Show clear algebraic working.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
