(x^2 + 4x + 8)(2x - 1) = 2x(x^2 + 4x + 8) - (x^2 + 4x + 8) = 2x^3 + 8x^2 + 16x - x^2 - 4x - 8 = 2x^3 + 7x^2 + 12x - 8
Answer:
223.34 m/s
Step-by-step explanation:
Given :
Travel time = 11 :23 pm to 1:00 a. M = 1 hour 37 minutes = (60 + 37) = 97 minutes = (97 * 60) = 5820 seconds
Distance between Seattle and San Francisco is
807.7 miles (culled from the internet)
807.7 miles = 1299867.1 meters
Average speed = Distance covered / Time taken
Average speed = 1299867.1 m / 5820 s
Average speed = 223.34486
Average speed = 223.34 m/s
To solve for X: First you multiply x and 6 then subtract 21 on both sides and then divide by 6
531 = ( X × 6) + 21
531 = 6X + 21
510 = 6X
85 = X
Hope this helps :)
