Answer:

(4x - 5)(5x - 4)

Step-by-step explanation:

20x² - 41x + 20

41 ± √1681 - 4(400) / 40

41 ± 9 / 40

5/4 or 4/5

Now using the zeros,

(x - 5/4) (x - 4/5)

(4x - 5)(5x - 4)

-3<2x+3< or equal to 5
Aliun [14]

Answer:

B

Step-by-step explanation:

-3 < 2x + 3 <= 5

-6 < 2x <= 2

-3 < x <= 1

such a condition is an "and" condition. both parts need to be fulfilled.

-3 < x and x <= 1

if you are still not seeing it :

-3 < x is the same as x > -3

now you see that B is the right answer.

x > -3 and x <= 1
