rate = distance / time Ok, part a is correct, try writing the answer as 2/5
rate = 2/5 = 0.4 in/s
rate = 0.4 in/s
Hi, I'm here is just that the pictures are small, I'm trying to read them
b)
Please upload a picture of part b like the last picture you sent of part a
2/5 = x/ 15
x = 15 x 2 / 5
x = 30/5
x = 6 inches
The result is 6
Here is all the work with it
Answer:
x = 1 ±2sqrt(5)
Step-by-step explanation:
2x^2-4x-9=29
Add 9 to each each side
2x^2-4x-9+9=29+9
2x^2-4x=38
Divide by 2
2/2x^2-4/2x=38/8
x^2 -2x =19
Complete the square
x^2 -2x + (-2/2)^2 = 19 +(-2/2)^2
x^2 -2x +1 = 19+1
(x-1)^1=2 = 20
Take the square root of each side
sqrt((x-1)^2) = ±sqrt(20)
x-1 = ±sqrt(20)
Add 1 to each side
x-1+1 = 1 ±sqrt(20)
x = 1 ±sqrt(20)
Simplifying the square root of 20
x = 1 ±sqrt(4)sqrt(5)
x = 1 ±2sqrt(5)
Huh this gives out no information to answer
Depends on how much people want there too be cooking books
