Answer:
What is the questions here? if you want area the answer is 3.
Step-by-step explanation:
For a perfect square
b² = 4*a*c
Comparing ax² + bx + c = 0 to x² + bx + 16
a = 1, c = 16
<span>b² = 4*a*c
</span>
<span>b² = 4*1*16
</span>
<span>b² = 64
</span>
b = √64
b = 8
The value of b = 8.
Absolute value tells how many spaces the number is from 0. And opposite numbers are negative numbers on the left side of 0.
