The milk is the dependent variable
Answer:
D = -4
E = 2
Step-by-step explanation:
The procedure for completing the square method is given as:
x2 + bx + c = 0
x2 + bx = -c
x2 + bx + (b/2)2 = -c + (b/2)2
Aolving the LHS simultaneously,
(x + b)2 = -c + (b/2)2
Find the square root of both sides,
(x + b) = sqrt(-c + (b/2)2)
So for the equation, x2 - 8x + 12
x2 - 8x = -12
x2 - 8x + 16 = -12 + 16
(x - 4)2 = 4
So square root both sides,
(x - 4) = 2
Comparing this to the equation given,
(x - D) = E;
D = -4
E = 2
The answer is J. Brainliest please :)
Answer:
22
Step-by-step explanation:
We can use the order of operations (PEMDAS), to solve this equation.
We must first multiply and divide, and order. This means we divide 12 by 3 and get 4, then multiply that by 2 and get 8. (30-12÷3×2,30-4×2,30-8). Now we just subtract 8 from 30 and get 22 as our answer.
