Answer:
x2 + 10x +25 = (x+5)^2
Step-by-step explanation:
x^2 + 10x
To complete the square
Take the coefficient of x
10
Divide by 2
10/2 =5
Square it
5^2 =25
Add it
x2 + 10x +25
The coefficient of x divided by 2 is the factor we add to x inside the square
(x+5)^2

Answer:
326.85 ft^2
Explanation:
The area of a circle is A=πr2
If we substitute the value of 10.2 feet into this formula we get 326.85 ft^2
A) 68.25+3x<80
b) subtract 68.25 from both sides of the inequality
3x<11.75 divide both sides by 3
x<47/12
Since x must be an integer, the greatest number of cartons that he can purchase is 3. Hope this helps:)
