2 answers:
Answer:
(13y+8)(y-x)
Step-by-step explanation:
13 - 5yx -8
we can solve above equation by using splitting the middle term
we can factorize it by splitting the middle term
13 - 5yx -8
=13 - 13yx+8yx -8
=13y(y-x)+8x(y-x)
=(13y+8)(y-x)
There are the two factors because the degree of the polynomial is 2
Hence, the correct answer is (13y+8)(y-x)

<h3>Answer:</h3>
In this question, we're trying to find how much Hermione spent on plums.
We know that:
- Hermione bought 9/10 of a pound of plums
- Plums cost $1.30 <em>per pound</em>
With the information above, we can solve the question.
Since we know that plums cost $1.30 per pound and Hermione bought 9/10 of a pound, we would multiply 1.30 by 0.90 in order to get the price Hermione bought the plums for. Hermione is pretty much paying 90% of the cost of a pound.
When you multiply, you should get 1.17
This means that Hermione spent $1.17 on 9/10 pound of plums.
