1) you can expand the brackets, simplify, set the equation = 0 and then do a double bracket factorisation.
2)
therefore Josh's solution is wrong asx = 7 and x= -1
Not sure if that's a multiplication or a composition. It doesn't matter. Both f and g have a domain of all real numbers. The domain of
is the same as the domain of g(x), all real numbers
Answer: all real numbers

answer is, handle. i think this is right??
Answer:
440 pounds
Step-by-step explanation:
The ratio of the total weight to the weight of apples is ...
(4 + 3 + 4) : 4 = 11/4
So, the total weight will be ...
total weight = (total weight)/(apple weight) × (apple weight) = (11/4)×(160 lb)
total weight = 440 lb

<em>Comment on the problem</em>
The problem doesn't say what the ratio is. We have to assume it is the ratio of weights. (It could be the ratios by volume, sugar content, cost, or any of a number of other factors.)
