Answer:
They subtracted the values incorrectly
Step-by-step explanation:
The formula for finding the distance between two points is this:

The person subtracted the variables incorrectly and subtracted x1 from x2 and y1 from y2 instead of the other way around.
To correctly solve it, do this:
Hope this helped!
Answer:
Step-by-step explanation:
b(a + 1) + a = b*a + b + a = ab + b + a
1) b(2a +1 ) = b*2a + b*1 = 2ab + b Not equivalent.
2)a + (a +1)*b = a + ab+ b Equivalent
3) (a +1)(b+ a) = a*(b +a) + 1*(b+a) = ab+ a² +b + a Not equivalent.
4) (a + 1)b + a = ab+ b + a Equivalent
5) a + b(a+1) = a +ab + b Equivalent
6) a + (a +1) + b = a + a + 1 + b = 2a + 1 +b Not equivalent.
7) a(b +1) + b = ab + a + b Equivalent

Answer:
15 combinations
Step-by-step explanation:
The fundamental counting principle states that if there are p ways to do one thing, and q ways to do another thing, then there are p×q ways to do both things. This means we need to multiply 3 by 5 to get the possible amount of combinations. This gets us 15. This means there are 15 combinations of bread and meat.
