Answer:
Step-by-step explanation:
2z^2(3z^2 - 7z - 20)
2z^2(3z + 5)(z - 4)
First we solve system to see what it indicates.
multiply first equation by 3 and subtract it from second.
it will become
3x + 3y = 72
after subtracting from second we get:
2y = 28
y = 14
x = 24 - 14 = 10
We can conclude that there are more 5 points question. there are 10 three point questions and 14 five point questions.
