Answer:

(x+8)²

Step-by-step explanation:

x² + 16x + 64 = (x+8)²

Jason can travel 24 3/4 miles in 1/2 hour. What is hi average speed in miles per hour?

eduard

Answer:

49 1/2 miles per hour

Step-by-step explanation:

To determine the average speed, we take the miles and divide by the hours

speed ÷ hours

24 3/4 ÷ 1/2

Change the mixed number to an improper fraction

24 3/4 = (4* 24+3)/4 =99/4

99/4 ÷ 1/2

Copy dot flip

99/4 * 2/1

99/2

Change to a mixed number

2 goes into 99 49 times (49*2 = 98) with 1 left over

49 1/2 miles per hour
