Aldo drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 8 hours. when aldo drove home, there was no traffic and the trip only took 5 hours. if his average rate was 21 miles per hour faster on the trip home, how far away does aldo live from the mountains? do not do any rounding.

Adriveway is 60-feet long by 6-feet wide. the length and width of the driveway will each be increased by the same number of feet. the following expression represents the perimeter of the larger driveway: (x + 60) + (x + 6) + (x + 60) + (x + 6) which expression is equivalent to the expression for the perimeter of the larger driveway? a) 2(x + 66) b) 4x + 33 c) 4(x + 33) d) 4(x + 132)

Use the x-intercept method to find all real solutions of the equation.x^3-10x^2+27x-18=0
