Answer:
x^2-3x=4
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4)+1(x-4)=0
(x+1)(x-4)=0
x=-1,4
x- intercepts in the point (-1,0) and (4,0)
Step-by-step explanation:
B. 3. Because if you have two people rolling a six sided die, with odd and even number contributions, you would divide 6 by 2. This is because there are TWO people going for TWO different types of numbers, odd and even. 6/2 gives us 3.
Hope this helps :)
