Question

Which number line represents all of the values of x for the equation x2 = 16?

A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on the number line, and all these are increments are labeled. A dot is shown on positive 4 and is labeled as p.

Answer 1

i think it is the third one

hope it helps

Answer 2

The given equation is

→x²=16

→x²-16=0

→(x-4)(x+4)=0

x=4, -4

p=4

q=-4

Option C

A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on the number line, and all these are increments are labeled. A dot is shown on positive 4, another dot is shown on negative 4, and are labeled as p and q, respectively.
