Step-by-step explanation:
Answer:
25 inches
Step-by-step explanation:
1. Information that is needed to solve the problem;
The formula for the perimeter is:
2(a+b) = P
where "a" is the length and "b" is the width.
2. Solving the problem;
Substitute the given values into the formula;
2( 5 + b ) = 58
Inverse operations;
2 ( 5 + b ) = 58
/2 /2
5 + b = 29
-5 -5
b = 25
Answer:

Answer:
25
Step-by-step explanation:
The number that needs to be added is the square of half the x-coefficient:
(-10/2)^2 = 25
_____

x = 5 ± 4√2
Answer: 
<u>Step-by-step explanation:</u>
"At least one girl" means P(1 girl) + P(2 girls) + P(3 girls) or 1 - P(all boys)
