Answer:
473
Step-by-step explanation:
The square surface area is 121 (11x11)
For the triangles, you do 16x11, which equals 176 and then divide by 2, to get 88. Since there are 4 triangles, I did 88x4 and got 352 and then added 121 to get 473
There are 12 parts to the ratio (1 + 3 + 8 = 12).
Divide 54,000 by 12.
54,000/12 = 4,500
Now multiply for each part:
1 = 4,500
3 = 13,500
8 = 36,000
You can check by adding them up (4,500 + 13,500 + 36,000 = 54,000).
So the ratio is 4,500:13,000:36,000
Hope this helps =)
17x(1-2y)
17x-34xy
because both expressions have a x, it would be easier to factor out the x first. but because 17 is a factor of 34 you can simply divide 34 by 17 and get 2. so you put it together to this,
17x(1-2y)
Because, 17x times 1 is 17x but 17x times -2y would be -32xy.
