It keeps taking the question out but hopefully the picture helps

c. 5

Step-by-step explanation:

Try each choice on the right side of the inequality, and see which one makes the inequality true.

a. 0

x(9 - x) = 0 * (9 - 0) = 0 * 9 = 0

10 < x(9 - x)

10 < 0

10 is not less than 0, so a. is out.

b. 1

x(9 - x) = 1 * (9 - 1) = 1 * 8 = 8

10 < x(9 - x)

10 < 8

10 is not less than 8, so b. is out.

c. 5

x(9 - x) = 5 * (9 - 5) = 5 * 4 = 20

10 < x(9 - x)

10 < 20

10 is less than 20, so c. works.

d. 10

x(9 - x) = 10 * (9 - 10) = 10 * (-1) = -10

10 < x(9 - x)

10 < -10

10 is not less than -10, so d. is out.

The only number that works is
