Assuming this picture is the graph, the answer would be
4,757 children
35,010 − 30,253 = 4,757<span> </span>
if a > 0, there are two possible solutions:

the square root of a square is the base in absolute value bars


if a = 0, that means x = 0. anything multiplied by 0 is 0
if a < 0, there are no solutions because anything squared has to be positive
Answer:
Hello,
Step-by-step explanation:
<u />
<u>Formula used (a+b)^2=a²+2ab+b²</u>

For number 19:
"at least 150" means either 150 ≤ ? or ? ≥ 150
plus 3 so +3x
The answer would be 150 ≤ 100 + 3x
Number 20:
A is at -2.5. The inverse is the opposite so 2.5
