Because of he parenthesis, the operation in it must be performed first.
So (16+66/2) should be performed FIRST.
Answer:
30
Step-by-step explanation:
The perimeter of this rectangle is calculated by adding width to length and that multiplied by 2
2*(3x+2x+2) = 54 do inside the parenthesis first
2*(5x+2) = 54 multiply inside the parenthesis by 2
10x + 4 = 54 subtract 4 from both sides
10x = 50 divide both sides by 10
x = 10
The length for PS is 3x
3*10 = 30
Answer:
Right angled and isosceles
Using the given formula speed = distance over time:
Speed = 70 miles / 3 hours
Speed = 23.33 miles per hour
Convert miles per hour to meters per hour:
1 mile = 1609 meters:
23.33 miles x 1690 meters = 37,543.33 meters per hour.
Now convert meters per hour to meters per second:
1 hour = 3600 seconds:
37,543.33 / 3600 = 10.4 meters per second.
