A1=bh/2

A2=2b*2h/2=2bh

A2/A1=2bh/(bh/2)

A2/A1=4bh/bh=4

So the area is quadrupled not doubled...

I really don't understand this. Would someone please send me on how to do this along with the answers?
patriot [66]
Easiest way:

Look at A and C. To get from A to C you need 6 steps to the right and 2 steps upwards. 
Slope means (in layman's terms) that how many steps you take upwards when you take 1 step to the right. 
In your case you take 2/6 steps, because it would take you 6 steps to the right to go 2 steps upwards.
A slope of 4 would mean that 1 step to the right is followed by 4 steps upwards. A slope of -5 means 1 step to the right, 5 steps downwards.

To get from A to E you need 9 steps to the right and 3 steps upwards. This means a 3/9 slope. The simplest form of it is 1/3. 
1/3 slope means that for every 3 steps to the right you take 1 step upwards. 

I hope this was understandable, this is how they taught me this in 5th grade more than a decade ago.

5k-2(3k + 4) = 5x + 4<br> help?
vazorg [7]
Use distributive property
5k - 6k -8 = 5x + 4
Combine like terms
-k - 8 = 5x + 4
add 8 to both sides
-k = 5x + 12
k = -5x- 12
