Answer:
19th day
Step-by-step explanation:
So say Lily was 1 when Lily was planted
First day Lily is 2
Second day Lily is 4
Third day Lily is 8
etc...
See the pattern?
The pattern is 2^x
On the 20th day, Lily was 2^20
So when Lily was half, Lily was 2^20 / 2
2^x = 2^20 / 2
2^x = 2^19
On the 19th day, Lily was half.
Answer:
9x,2,8y
Step-by-step explanation:
Answer:
-19
Step-by-step explanation:
1) substitute a with 2 and b with 5
(3 + 2)^2 * (4-5) + √36
2) solve the brackets and the square root
(5^2) * (-1) + 6
3) solve the power
25 *(-1) + 6
4) solve the multiplication
-25 + 6
5) solve the sum
- 19
This is a pythagorean triple --> 3-4-5
Although you notice it is doubled but with the same pattern --> 6-8-10
Thus, the hypotenuse is 10.
