A.
Step-by-step explanation:
you can buy a negative amount of packages so that rules out B and D

Answer:
400 = (x - 10)²
x² -20x -300 = 0
x = 30 and x = -10
Length side of the garden = 20 feet
Step-by-step explanation:
Given:
Area of square garden = 400 square feet
Length side of the garden = (x - 10) feet
Find:
Length side of the garden
Computation:
Area of square = side²
Area of square garden = Length side of the garden²
400 = (x - 10)²
400 = x² -20x + 100
x² -20x -300 = 0
x² -30x + 10x -300 = 0
x(x - 30) + 10(x - 30) = 0
(x - 30)(x + 10) = 0
So,
x = 30 and x = -10
Use x = 30 positive number
Length side of the garden = (x - 10) feet
Length side of the garden = (30 - 10) feet
Length side of the garden = 20 feet
I'm not exactly sure how to answer this question without knowing the number of scholars. However, if you do know the number of scholars, you can divide that number by 9. The quotient will give you the amount of chocolate each scholar can receive.
(56*a*b)/b= 56a
Remember that multiplying by b and then diving by b cancels out, leaving only 56a left
Final answer: 56a
