Answer:
2a2 • (a + 1) • (a - 3)
Step-by-step explanation:
It is something that is not consistent. Having a fixed pattern or liable to be changed.
First find the area of two sides (Length*Height)*2 sides, 70. Then find the area of adjacent sides (Width*Height)*2 sides, 60.9. And then find the area of ends (Length*Width)*2 ends, 87. Lastly add the three areas together to find the surface area, 217.9.
Answer:
lets figure out how many in total
10 + 23 + 57 = 90
10/90
11%
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
These are similar triangles, so the ratio of their sides is the same for each side.
AB = 8 and BD = 10
So, the ratio is 8:10 or 4:5
Because the triangles are similar....
The ratio of AC:CE is also 4:5
12:15 = 4:5
So, 12 is the answer!
