Answer:

Step-by-step explanation:

x^2 = 6x + 27

x^2 - 6x = 27

x^2 - 6x + 9 = 27 + 9

(x - 3)^2 = 36

x - 3 = ± √ 36

x = 3 ± 6

x = 3 + 6 = 9

x = 3 - 6 = -3

solutions are : x = -3 or x = 9

The length of a rectangle is 5 times it’s width. If the perimeter of a rectangle is 72 m, find its area
Olenka [21]
X = width. the perimeter of a rectangle is 2*length + 2*width, so the perimeter of this rectangle is 2x + 2(5x) = 72. distribute the two to get 2x + 10x = 72. so 12x = 72. divide by twelve to get x = 6. the width is six, so the perimeter (5x) is 30. the area of a rectangle is length times width, 30*6, so the area is 180 m.
