The product is: 25x^2-5xy-6y^2
We need the graph to answer!
First calculate th feet of lace she haven't used.
9 - 3 = 6 ft
now we can convert feet into yard. we can divide the amount into 3 because it says 3ft is 1yrd
6 / 3 = 2 yards
Answer:
x must be a negative i mean it has to how tfk do you get zero at an answer what kn the world
Because there are 4 students who passed in all subjects, we can say that only 2 students passed in English and Mathematics only, only 3 students passed in Mathematics and Science only, and no one passed in English and Science only.
Given that we have deduced the number of students who passed in two subjects, we can now solve for the number of students who passed only one subject.
English = 15 - (4 + 2 + 0) = 9
Mathematics = 12 - (4 + 3 + 2) = 3
Science = 8 - (4 + 3 + 0) = 1
1. In English but not in Science,
9 + 2 = 11
2. In Mathematics and Science but not in English
3 + 3 + 1 = 7
3. In Mathematics only
= 3
3. More than one subject only
3 + 4 + 2 + 9 = 18
It will really be helpful if you draw yourself a Venn Diagram for this item.
