9x^2 -c =d

add c to each side

9x^2 = c+d

divide by 9

x^2=(c+d)/9

take the square root on each side

x = +- sqrt ((c+d)/9)

simplify

x = +- 1/3 sqrt (c+d)

Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)

Maria’s family hosts a barbeque every month in the summer. In May, they bought 3.2 pounds of hamburger and 3 packages of hot dog
Sindrei [870]
Given:

May:
hamburger: 3.2 pounds * 4.25 = 13.60
hotdogs:     3 packages * 4      = 12
Total cost: 13.60 + 12 = 25.60

June:
hamburger: 3.2 pounds * 1 1/2 = 4.8 pounds * 4.25 = 20.4
hotdogs:      3 packages * 1/3    = 1 package * 4        =   4
Total cost: 20.4 + 4 = 24.4

25.60 - 24.40 = 1.20

They spent more on May by $1.20. Choice C.
