What is the equation for the perpendicular that passes through the point (-1,-2) ?

Perpendicular with respects to what?

You can't find it with only a point, you also need a slope to know which line is which.

There are an infinite number of lines that go through any point. Each has a slope, without slopes, we cant solve such a question.

It's line asking, how old is Jane's dog?

Who knows man? There's like thousands of Janes, which one is the one?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
