Astudent drove to the university from her home and noted that the odometer reading of her car increased by 23 km. the trip took 41.4 min. what was her average speed in km/h

To solve this problem you must apply the proccedure shown below:

1. You need to apply the following formula:

2. You have that the distance is and the time is . Therefore, you only have to substitute values into the formula. So, you obtain:

The answer is:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
