Assuming you want to factor, then you would use the factor by grouping method
x^2+4x + xy+4y
(x^2+4x) + (xy+4y)
x(x+4) + y(x+4)
(x+y)(x+4)
Therefore, x^2+4x + xy+4y factors to (x+y)(x+4)
Answer:
C=6p
Step-by-step explanation:
The cost (c) will be by itself since that is the answer you are looking for. 6p is grouped together because for every pound you pay $6. For example if you had 2 pounds of chocolate. You would multiple $6 by 2 and your cost would equal $12
Yes you just have to cross multiply
