Answer:
I came up with 412cm^2
Step-by-step explanation:
10*12+(12*2)2+(10*2)2+6*8+(8*3)2+(6*3)2+(12*10-6*8)
3.5 : 5
7 : 10
14 : 20
17.5 : 25
At that rate, she can read 17.5 pages in 25 minuets.
Divide both 7 and 10 by 2, which gets 3.5 and 5
5 * 5 = 25
5 * 3.5 = 17.5
Therefore, in 25 minuets, she can read 17.5 pages.
6×ax+6×by =6ax+6by =3a+2b,6×bx-6×ay=3b-2a=6bx-3a+2b
