Question

Which values are solutions to the inequality below? Check all that apply.

x² < 16
A. 5
B. 4
C. 3
D. -1

Answer 1

C and D are solutions

`a \\ \\ {5}^(2) > 16 \\ \\ b \\ \\ 16 = 16 \\ \\ \\ c \\ \\ \\ {3}^(2) < 16 \\ \\ { - 1}^(2) < 16`

Answer 2

To find the values that satisfy the inequality x² < 16, we need to determine which numbers, when squared, are less than 16.

Checking the given options:
A. 5² = 25, which is not less than 16.
B. 4² = 16, which is not less than 16 (it is equal).
C. 3² = 9, which is less than 16.
D. (-1)² = 1, which is less than 16.

Based on this analysis, options C (3) and D (-1) are the values that satisfy the inequality x² < 16.
