Ineed 1-17 for factoring expressions

The answer to your question is:

Step-by-step explanation:

1.- 2x(2x + 5)

2.-  2x(8 - x)

4.- (x + 3)(x + 1)

5. (x - 5)(x - 3)

7.- (x - 8) (x + 7)

8.- (x - 3)²

10.- -(x² - 12x + 32) = -(x - 8)(x -4)

11.- -(x² + x + 20) = -(x - 5)(x + 4)

13.- 2x(2x + 3)

14.- (x + 12)(x + 2)

16.- (2x - 3)(x + 2)

17.- (x + 5)(3x +1)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer: 2530

hope this
