Please help i cant figure out how to do this stupid problem

(x + 8)^2 = 1.

Step-by-step explanation:

We use the identity x^2 + ax + b =  (x + a/2)^2 - (a/2)^2 + b.

x^2 + 16x + 63 = 0

(x +16/2)^2 - (16/2)^2 + 63 = 0

(x + 8)^2 - 64 + 63 = 0

(x + 8)^2 - 1 = 0

(x + 8)^2 = 1.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
