Answer:
(2k+1)(k+3)
Step-by-step explanation:
14k²+49k+21
simplify by dividing the whole equation by 7
2k²+7k+3
factorise
(2k+1)(k+3)
Triangle OPQ is shown below with line RS passing through points R and S:
Triangle OPQ is shown with point R lying on side OP and point S lying on side OQ Line RS is perpendicular to side OQ.
If triangle OPQ is dilated about the center of the triangle to create triangle O'P'Q', what can you conclude about segments RS and R'S'? (6 points)
Segment O'Q' is perpendicular to segment R'S'. Line RS is parallel to line R'S'. Line RS is perpendicular to line R'S'. Point P' passes through line RS.
We want the seconds to be converted in hours to work out the speed, so:
7200Seconds /60 / 60 =2 Hours
150 / 2 = 75
Therefore the car travels at 75kmh.
Answer:
Rates are ratios that are renamed so that one of the numbers is 1. It is usually the denominator of the original ratio.
You can determine your speed that is Speed = (distance/Time). Mind you in this cast time should be in hour, so 30 min - 1/2 hour or 0.5 Hour
Your speed is 5/0.5 = 10 mi/hour
