B, because 40 and 40 make 80 and 180-80=100<span />
Answer:
40%
Step-by-step explanation:
You do 10/25 and to make that a fraction you have to make the denominator 100 so we multiply the numerator and denominator by 4. Which gets us 40/100 or 40%.

Answer:
B
Step-by-step explanation:
you can use foil and the graph,
because you can see (in the graph) that the lines intersect at 1 and 4.
just use foil to help figure out which matches the slope.
something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be
-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.
