Answer:
x = -3 and x = -2
Step-by-step explanation:
-3 +3 = 0
-3 + 3 = 1
thus that means 0 + 1 = 1
Answer: 15 cases
Step-by-step explanation:
1 gallon = 4 quarts
Hence from 30 gallon oil drum, 30 x 4 = 120 quart-size bottles can be filled.
One case will pack 8 quart size bottles.
Hence number of cases = 120/8 = 15 cases

Answer:
x ∈ {2.07014981016}
Step-by-step explanation:
The equation can be rewritten as ...
√x = 18-8x
x = 324 -288x +64x²
64x² -289x +324 = 0
x = (289 ±√577)/128 ≈ {2.07015, 2.44548}
Since √x must be positive, we know that ...
18 -8x ≥ 0
x ≤ 18/8 = 2.25
The larger of the above solutions is extraneous, so the solution set is ...
x ∈ {(289 -√577)/128} ≈ {2.07015}
Answer:
(x = -20) if what your saying is 6 = -2x - 4 and (x = -16) if what your saying is x = -2 x 6 - 4
