1) BC intercept y at (2,1) (given)
2) The slope of AB ===> m= (-1 - 1)?(14 - 2) ===> m = - 1/6
2) the slope of BC that is perpendicular to AB is the inverse of (1/6) & change the sign, that is 6. To find the function y, apply the formula:
y-y1) = m(x-x1) ===> y-1 = 6(x-2) [the coordinate of B] ==> y= 12x - 11
3) if y= 13, replace y by 13 in the equation:
13 = 12x -11 ===>x = 2
(5x-3)(4x+5) the last step you have to look at the two terms that you are adding together the 4x(5x-3) and the 5(5x-3) and see what is similar. well the whole bracket is the same the 5x-3 so factor that out and collect the other leftover terms so the 4x and the +5 and thats what goes in the second bracket

I think u should divide 8 and 10 then u will get your answer hope that helps
