I’m not sure if 1/6 is suppose to be 16 so if it is not let me know
A= 126
A= a+b/2 x h
12+4 / 3 x 16
Answer:
slope1 : 7, slope 2 = 3 solution: (2,5)
Step-by-step explanation:
I simplify some steps
pair 1: x1 0 2
y1 -9 5 ........ -9, y1 intercept
pair 2: x2 0 2
y2 -1 5 ........ -1, y2 interept
2 pairs meet at (2,5)
y=7x-9 ......A
y=3x-1 ......B
A-B 0=4x-8
4x=8
x=2
y=5
slope 1=( y2-y1) / (x2-x1) = (5- -9)/(2-0) = 14/2 =7
slope 2 = (5 - -1) / (2 - 0) = 6/2 = 3
Answer:
The solutions are given below:
Step-by-step explanation:
x(x-3)+4(x²+2)
= x²-3x+4x²+8
= x²+4x²+8-3x
= 5x²+8-3x
2(a+5)-3(a+7)
= 2a+10-3a-21
= 2a-3a+10-21
= -a-11
xy(x²yz-xy²z+xyz²)
= x³y²z-x²y³z+x²y²z²
-4(a²-2a+8)
= -4a²+8a-32

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.
