OpenStudy (anonymous):

easy, bit i feel like its a trick questions lol CX

OpenStudy (anonymous):

but*

OpenStudy (unklerhaukus):

parallel lines have the same slope m_1=m_2, perpendicular lines have negative inverse slopes m_1=-1/m_2

OpenStudy (agent0smith):

Looks right.

OpenStudy (anonymous):

XP can you look at this one too

OpenStudy (anonymous):

OpenStudy (agent0smith):

x can't be 100, f(x) is the perimeter and the perimeter is 100. x is only the width... set f(x) = 100 and solve for x.

OpenStudy (anonymous):

ohh so b, 2*24 = 48 52 + 48 = 100

OpenStudy (agent0smith):

Yep, b

OpenStudy (anonymous):

Annd this is the one im stuck on D:

OpenStudy (anonymous):

ty for all your help :P

OpenStudy (agent0smith):

Just round each to the nearest tenth eg 1.56 rounds to 1.6

OpenStudy (anonymous):

5.2?

OpenStudy (anonymous):

Wait, 22.1 ?

OpenStudy (agent0smith):

Where did 22.1 even come from...? Round each to the nearest tenth. Choose the biggest.

OpenStudy (anonymous):

5.5?

OpenStudy (agent0smith):

eg 1.56 rounds to 1.6 2.57 rounds to 2.6 10.12 rounds to 10.1 6.75 rounds to 6.8

OpenStudy (anonymous):

So 5.35 = 5.5 because the 3 isn't above 5 so its ohhh wait, 5.3?

OpenStudy (agent0smith):

****6.75 rounds to 6.8*****

OpenStudy (agent0smith):

6.75 does NOT round to 6.9

OpenStudy (anonymous):

Yes, the 5 helps the 7 go up by 1

OpenStudy (anonymous):

5.4 fml...

OpenStudy (anonymous):

right? D:

OpenStudy (agent0smith):

yes

OpenStudy (anonymous):

so i should put 5.4 as my final answer? Doesn't 5.29 = 5.3 ?
