Bell:
1 hour = 10 miles
4.5 hours = 10 x 4.5 = 45 miles.
Kristin:
1 hour = 14 miles
4.5 hours = 14 x 4.5 = 63 miles
Difference in distance = 63 - 45 = 18 miles.
Answer: They will be 18 miles apart.
Answer:
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)
Step-by-step explanation:
(X^2 + x - 6) (2x^2 + 4x) =
Let's open the brackets carefully
x^2 * 2x^2 + x^2*4x + x*2x^2 + x*4x - 6*2x^2 - 24x
= 2x^4 + 4x^3 + 2x^3 + 4x^2 - 12x + 24x
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)
Answer:
Mean = 33
Step-by-step explanation:
Mean = sum of scores /no of scores
Mean = 132/4
Mean = 33
Answer:
Set 1: 3(2x)
Set 2: 1/2 (-4x)
Set 3: 2 (12x + 4y)
Step-by-step explanation:
Set 1: 3(x+2) and 3x+6 are the same//3(x+2) =3x+6
Set 2: 1/2 (2x - 6) and x - 3 are the same//1/2 (2x - 6) = x-3
Set 3: 24x + 8y and 8(3x + y) are the same//2x+8y = 8(3x + y)
