Answer:
Step-by-step explanation:
If the rectangle show one side of length 5 x +2, and another side of length x - 4, then the area of this rectangle (given by the product of the sides' length) is:
which is already written in standard form.
10+9 x 8 = 100+50+2 (152)
Using the speed - distance relationship, the distance traveled by Joanne would be 55.714 km
Kuzi's speed :
- <em>16</em><em>/</em><em>2</em><em> </em><em>=</em><em> </em><em>8km</em><em> </em><em>/</em><em> </em><em>hr</em><em> </em>
Joanne's speed :
- <em>6km</em><em>/</em><em>hr</em><em> </em>
Let time taken = <em>t</em>
<u>Total</u><u> </u><u>distance</u><u> </u><u>traveled</u><u> </u><u>:</u>
8t + 6t = 130
14t = 130
t = 130/14
t = 9.2857142 hours
<u>Therefore, distance traveled by Joanne</u> :
Joanne's speed × time
6 km × 9.2857142 = 55.714 km
Therefore, distance traveled by Joanne will be 55.714 km

perimeter of rectangle = 20+20 +15+15 = 70 yards = 70*3 = 210 feet
210/5 = 42 seconds
Courtney walks it in 42 seconds
the diagonal = 15^s + 20^2 = 225+400=625
sqrt(625) = 25 yards
Natalie walks 20 +15 +25 = 60 yards
60*3 = 180 feet
180 /5 =36 seconds
42 - 36 = 6 seconds faster
5% of 60 dollars is 3 dollars.
