Solve (x + 9)2 = 25.

Apply the square root property of equality:
Isolate the variable.

StartRoot (x + 9) squared EndRoot = Plus or minus StartRoot 25 EndRoot
If x + 9 = 5, then x =
.

If x + 9 = –5, then x =
.

-4 ; -14

Step-by-step explanation:

x+9 = 5

x = 5-9 = -4

x+9 = -5

x = -5-9 = -14

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
