3ay(a + 2y)^2
=3ay(a + 2y)(a + 2y)
=3ay (a^2 + 2ay + 2ay + 4y^2)
= 3ay (a^2 + 4ay + 4y^2)
= 3a^3y + 12a^2y^2 + 4y^3 a)
If to find the area of a triangle is to multiply 1/2 times the measure of the base times the height we need to make that equals to 18 since it’s already given. So 18=1/2 * ((h+1)*6)
Now we distribute
18 = 1/2 (6h + 6)
18 = 3h + 3 (Now we subtract 3 from both sides)
15 = 3h (now we divide both sides by 3)
5 = h
h = 5

Answer:
598 books
Step-by-step explanation:
Let x be the number of books in the 3rd pile. We will have then:
1st pile: 2x + 10
2nd pile: 2x
3rd pile: x
3000 = (2x + 10) + (2x) + (x)
3000 = 5x + 10
3000 - 10 = 5x
2990 = 5x
2990/5 = x
x = 598 books in the third pile!
We can check that:
3000 = 2*598 + 10 + 2*598 + 598
3000 = 1196 + 10 + 1196 + 598
3000 = 3000 CHECK!
Answer:
30.2 - 13.7=n
Step-by-step explanation:
To get how far he ran you have to subtract 30.2 from 13.7 therefore giving you 16.5 which will be the total distance he ran after lunch.
What are you looking for how many they took or how many in total is left
