Answer:
(x-9)(x+4)
Step-by-step explanation:
When factoring, you use the formula ab ÷ c to find what you can multiply to get (in this case) -36 that you can add to get -5. The answer is -9 and 4.
20% of 160= 32
160-32= 128
The new amount is 128 bananas.
If 30 textbooks weigh 144, you do 144/30 to calculate each unit
So the answer is 4.8
