Answer 1

Can you help with this?

Answer 2

2l+8=28
a+2l=28

Answer 3

l=10
a+10=28
a=18

Answer 4

Alright I got that. What about this one

Answer 5

@AlexandervonHumboldt2

Answer 6

hmm i dont know @campbell_st

Answer 7

so find the slope of BC the altitude is perpendicular to to BC

you need to find the slope of the altitude... and the line passes through A

so you have a point and a slope... so you can find the equation.

Answer 8

@AlexandervonHumboldt2 can you stop giving answers.

Answer 9

-4/3

Answer 10

Okay A.. haha I knew that O_O thanks

Answer 11

Wait... its supposed to be in standard form not slope int form

Answer 12

correct..

Answer 13

Is it still correct?

Answer 14

well the slope of BC is correct... what is the slope of the perpendicular

Answer 15

Which is the perpendicular?

Answer 16

so if you know the slope of BC, the slope of the line perpendicular to BC is the negative reciprocal...

Answer 17

So postive 4/3.

Answer 18

But since it needs to be in standard form it would be B?

Answer 19

close its positive, but what is the negtative reciprocal of- 4/3

its

Answer 20

Oh. Uh 3/4

Answer 21

and B is the correct answer

Answer 22

I have another question with points, do you have time for that?
