Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The quotient of y^2-16 y+4
divided is
4y-16 16y

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

what the question so we can you out
