Answer:
(x+4y)(x-4y)
Step-by-step explanation:
Since

we can see that

c) alternate hypothesis
Step-by-step explanation:
4/7,8/14,12/21,16/28,20/35,24/42,28/49,32/56,36/63,40/70 and so on are equivalent fractions to 4/7
If x=students, the equation would be x=12 (x is less than of equal to twelve). I don’t know what you mean by constraints; perhaps if you explain more, I could help?
