I can’t figure this out I need the answer
fredd [130]

Answer:

  • Area 2 = 72 cm²
  • CD = 7 cm

Step-by-step explanation:

For similar figures, side lengths (and any other linear measure) are proportional. Areas are proportional to the square of the scale factor for side lengths.

  Perimeter 1/Perimeter 2 = CD/EF

  21/18 = CD/6

  CD = 6(21/18)

  CD = 7 . . . cm

__

  Area 2/Area 1 = (Perimeter 2/Perimeter 1)²

  Area 2/98 = (18/21)²

  Area 2 = 98(6/7)²

  Area 2 = 72 . . . cm²

Complete the square to solve the equation below.
Vinil7 [7]

9514 1404 393

Answer:

  B.  x = -6, x = 4

Step-by-step explanation:

The constant on the left wants to be 1, the square of half the x-coefficient. We can get it to be that value by adding 8 to the equation.

  x² +2x +1 = 25

  (x +1)² = 25 . . . . . . . rewrite the left side as a square

  x +1 = ±√25 = ±5 . . . . take the square root

  x = -1 ±5 . . . . . . . . . subtract 1

  x = -6 or x = 4
