Answer:The correct answer among the choices given is option 2.
Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
5x^2 + 27x + 13x = 14
5x^2 + 40x = 14
2. Make sure that the coefficient of the x^2 term is 1.
5(x^2 + 8x) = 14
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
5(x^2 + 8x + 16) = 14 + 80
5(x+4)^2=94

I did this on a test last week and i got this question right.
7×3=21 so he has 7 more lawns or 2 1/3 months
Answer:
13
Step-by-step explanation:
(x + 3)^3/2 = 64
√(x + 3)^3 = 64
(x + 3)^3 = 64^2
(x + 3)^3 = (4^3)^2
(x + 3)^3 = (4^2)^3
Same exponent
So
x + 3 = 4^2
x + 3 = 16
x = 13
100. You would divide the original amount of crackers by 240, then multiply by the new amount of crackers.
