if m∠2=(4x+5)° and m∠4=(x2−27)°, solve for x.

Since the area of the square is the square of its side then, the given equation 4x² -12x + 9 is a square of a binomial. the factors are,                                    4x² - 12x + 9 = (2x + 3)²the side of the square is 2x + 3.the area of the rectangle is length times width, two different measurements. the expression, 16x² - 9y² is the difference of two squares. the factors are,                                        16x² - 9y² = (4x + 3y)(4x - 3y)thus, the measures of the sides of the rectangle are 4x+3y and 4x-3y
