Answer:
(2x+3)(x+1)
Step-by-step explanation:
First you would have to find the distance it's going per hour.

You will then get the answer of 200 m/hr. You can then plug in 200 m/hr to find how far the jet could fly in 10 hours

You're final answer should be 2,000 miles
The second option is true: 3/6= 4/8
Not sure what the length of the rectangle is but to find perimeter of a rectangle you can use the following formula
2w+2l= perimeter
The reason we multiply both the length and width by two is because there are two ends of the width and two ends of the length.
The other formula that would also work is as follows
w+w+l+l= perimeter
