Answer:
(24x+9)yd
153yd
Step-by-step explanation:
The perimeter is the sum of all the sides, so put all the sides together.
(7x+3)+(6x+3)+(6x+3)+(5x)
7x+6x+6x+5x+3+3+3
24x+9
IF x=6:
(24(6)+9)yd
(144+9)yd
153yd
Answer: option 4 is the correct answer.
Step-by-step explanation:
The graphs shown in the photo are plots of distance versus time.
Distance travelled = speed × time
On a run, Natasha ran for 1 1/4 hours at a speed of 6 miles per hour. The distance that she covered would be
6 × 1.25 = 7.5 miles
She then rested for 1/4 hour. This means that her speed is 0 and the distance covered is also 0 miles.
She then ran for another hour at a speed of 5 miles per hour. Distance covered would be
5 × 1 = 5 miles
Total time spent would be
1.25 + 0.25 + 1 = 2.5 hours
Total distance covered would be
7.5 + 5 = 12.5 miles
Therefore, the 4th graph best represents the distance she traveled
Answer: k = 3
-2k - 4k = -18
-2k - 4k = -18
-6k = -18
k = -18/-6
k = 3
