Solve a(4a+5)−8=0 by using the Quadratic Formula. (Use a comma to separate multiple solutions.)

     x=−5/8 ±3/8

     x=0.921165

     x=−2.17116

Step-by-step explanation:

After solving a(4a+5)-8=0

Your Welcome

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
